Size Guide

Last updated: October 1, 2026

1. Named sizes and measurements

The catalog offers S, M, L, XL, 2XL, 3XL, 4XL and 5XL. Those labels are choices, not verified measurements. A medium in one garment can differ from a medium in another. We do not publish a made-up size table or borrow dimensions from a reference brand. Ask support for the exact garment measurements before ordering if a particular fit is important.

2. Choose a comparison garment

Use a jersey or top you already like as the starting point for a fit question. Lay it flat without stretching and note how it fits when worn. A body measurement and a flat garment measurement are different figures; say which one you are providing so support can compare the appropriate information.

3. Useful points to compare

Common garment comparisons include chest width, body length and sleeve dimensions. Describe the measuring points you used rather than sending an unexplained number. Do not convert a flat width into a fit guarantee without checking the garment shape and the ease you prefer. Exact measurement instructions depend on the confirmed jersey construction.

4. Fit preference and layers

Tell support whether you prefer a closer fit, a relaxed fit, or room for a layer underneath. The same named size can feel different when worn over another garment. The styling image shows one visual combination; it does not establish a measurement chart or promise the same fit on every wearer.

5. Before adding to the bag

Select the intended size and check that it appears correctly in the bag. Review the choice again before checkout. If a measurement is unresolved, ask before ordering rather than choosing from a guessed chart. A return or exchange is available under the 60-day policy, but a careful fit check can avoid an unnecessary shipment.

7. Start with the fit you want

A useful size decision begins with your preference, rather than with a number on a label. Think about how you want the jersey to sit at the chest, shoulders and hem. Do you want a closer silhouette, an easy everyday fit or space for another top underneath? Those preferences can lead two people with similar body measurements to choose differently. Describe the intended fit when you ask support for a comparison. A styling photograph can help you understand the visual direction, but a photograph of one person cannot establish the fit on every body. Camera angle, pose and the layer beneath the jersey all affect how a garment appears. Use the image as appearance guidance and use confirmed measurements for dimensions.

8. Pick a garment that provides a fair comparison

Choose a garment you actually enjoy wearing and that has a similar intended role. A tightly fitted stretch top is a poor comparison for a roomier sports jersey if you expect both to feel identical. A heavy coat is also a poor starting point because its construction includes space for several layers. A jersey or simple short-sleeve top usually gives more useful context. Before measuring it, note whether it has been washed, whether it has stretched with wear and whether the fit has changed. The comparison describes your existing garment; it does not prove that the new jersey uses the same fabric, stretch or construction. Make that distinction clear in your message.

9. Prepare a flat measuring surface

Place the comparison garment on a clean, flat surface with enough room for the body and sleeves. Smooth it gently so folds do not shorten the measurement. Do not pull the fabric tight or stretch the seams to create a larger number. A flexible measuring tape helps follow the garment, but keep it straight when you are measuring a straight span. If you use a ruler, take care when joining several short measurements because small gaps can add up. Record the unit next to every figure. A number such as 24 without inches or centimeters is ambiguous and can lead to an incorrect comparison. Measure twice and note any difference before sending the result.

10. Describe chest width precisely

A flat chest width is measured across the body of a garment, not around the person wearing it. Tell support where your tape begins and ends, for example across the garment near the underarm seams. Different suppliers may use a specific offset from the seam, so your measuring points matter. Do not assume that doubling a flat width gives a complete fit guarantee. The shape of the armhole, side panels, fabric behavior and your preferred ease also matter. If support provides a garment chest width, compare it with the same type of measurement from your own garment. If you instead provide a body circumference, label it as a body measurement so it is not mistaken for a flat garment width.

11. Explain body length and the desired hem position

For a length comparison, identify the upper and lower measuring points. A measurement from a shoulder near the neckline differs from one taken from the center back of the collar. Record how your comparison garment sits when you wear it: above the hip, at the hip or lower. That description is useful alongside the measured length. A jersey can look shorter in a photograph if it is tucked, lifted by a pose or layered over another garment. Do not treat a photographed hem position as a dimension. Ask for the confirmed length and measuring method of the design you are considering, then compare it with your preferred garment using corresponding points.

12. Check the upper-body shape

Chest width alone does not describe the entire upper body. The shoulder line, sleeve opening and armhole can affect how a garment feels when you move. When one of these areas matters to you, tell support which part of the fit you want to understand. A wide chest measurement does not automatically mean a wide shoulder or sleeve opening. Likewise, a garment can have a roomy body and a more defined neckline. The exact construction needs to be confirmed for the jersey rather than inferred from another product or a reference shop. If you have a comparison garment that feels comfortable through these areas, explain what you like about it.

13. Treat sleeve measurements as a separate question

A sleeve can be measured from different starting points, including the shoulder seam or a point near the neckline. Those measurements are not interchangeable. If sleeve length is important, explain the method used on your comparison garment and ask for the corresponding method on the jersey. The opening around the arm is another dimension and should not be confused with sleeve length. A styling image may show a sleeve resting at a particular position, but the position changes with arm angle and body shape. Use the visual to understand the design treatment, such as bands or panels, while keeping the actual fit comparison tied to confirmed dimensions.

14. Convert units carefully

Keep your original measurements in one unit whenever possible. If you convert between inches and centimeters, use the same conversion method for every figure and avoid rounding one measurement much more aggressively than another. A rounded figure is an approximation, so keep the original available when asking support. Do not add an invented tolerance to a chart that has not been supplied. Manufacturing tolerances, if relevant, need to come from the confirmed garment source. If support gives a range or a tolerance, ask what it applies to and whether it refers to a garment dimension or a measuring variation. Clear units and measuring points are more useful than a long list of unexplained numbers.

15. Compare the intended layering

A jersey worn over another top may feel different from the same jersey worn alone. Consider the layer you actually plan to use, including its thickness and shoulder shape. A light tee and a bulky hoodie do not take the same amount of room. You do not need to guess a larger named size solely because a styling image includes a layer. Instead, compare the confirmed garment dimensions with a combination you already find comfortable. Tell support that layering is part of your plan. The aim is to understand the space you prefer without inventing a rule that everyone should size up or down. That decision depends on the garment and the wearer.

16. Avoid assumptions from another brand

A familiar letter size can be a useful starting point, but it is not universal. Brand charts may use different body measurements, garment measurements, fit categories or grading. The size options in this catalog are not copied from a licensed team shop. Do not use the reference shop chart as proof of Bold Jersey dimensions. If you know the dimensions of a jersey you already own, those actual measurements are more useful than the label alone. Include both the label and the figures when asking a question, and say whether the existing fit is close, relaxed or oversized. Support can then explain what confirmed information is available for the item you are considering.

17. When you are between two named sizes

Being between sizes means you need to compare the fit differences that matter to you. It does not establish a universal instruction to choose the larger or smaller label. Look at the confirmed chest and length measurements, then consider your preference for room and the layers you intend to wear. If the difference between two options is not available, ask for it before ordering. A useful question is whether the relevant garment dimensions are known for both sizes, rather than whether one letter is usually better. Explain the fit you prefer and the comparison garment you used. This keeps the answer tied to your decision rather than to a guessed rule.

18. Review the graphic placement with the size question

The number, chevron, side panel or sleeve band is part of the design appearance. A generated mockup shows the intended composition, but it does not provide a verified print-placement tolerance for every named size. If the relationship between the graphic and the garment dimensions matters to you, ask support what is confirmed for your selected option. Do not assume a graphic scales in exactly the same way across S through 5XL. The product gallery should help you identify the design feature you mean so your question can be specific. Reference the full-item or detail image and describe the area, rather than asking about an undefined part of the jersey.

19. Check the selection before checkout

Choose the size on the product page and review the price and item information shown for that selection. When you add the jersey to the bag, check the line item for the design, size and quantity. A selected size can remain from an earlier visit or from a copied product link, so do not rely on memory. If you change the selection, review the bag again to make sure it contains the option you intend. Remove an accidental duplicate rather than assuming the checkout will combine it. The final check is a practical step that reduces avoidable size corrections and keeps the order record aligned with your actual choice.

20. If you notice a size mistake after ordering

Send a change request promptly with the order number, the current size and the intended replacement. The working window is 24 hours, provided the order has not shipped. Support must check the current stage and confirm whether the change is possible. A message requesting a correction does not itself update the order. Keep the reply that confirms the outcome and check that it names the right design and size. If the parcel has shipped, use the return or exchange process after delivery rather than assuming it can be recalled. The separate cancellation and returns policies describe these different stages.

21. If the fit is different from what you expected

You may request a return within 60 days of delivery for any reason, including a size preference. There is no restocking fee. For a change-of-mind size exchange, you pay the return postage and we pay to send an approved exchange item out. If the item is incorrect or not as described, the return-shipping arrangement is covered by the store as explained in the returns policy. Contact support before sending the jersey, identify the order and selected size, and wait for the approved route. A useful fit explanation can also help identify whether an alternative option addresses the issue, but an exchange still depends on availability.

22. A concise sizing message you can use

A useful sizing request identifies the design and SKU, the named size you are considering, your preferred fit and the comparison measurements. State the unit and measuring points for chest width and length. Add a sleeve or shoulder question only when it matters to your choice. Say whether you intend to layer the jersey over another garment. You can write these facts in a short paragraph or a simple list. Do not send private body photographs or identity documents to ask about a fit. The goal is to clarify the relevant garment dimensions and the way you want to wear it, while keeping personal information limited to what the question needs.
