I remember the first time I ordered a concert tee online and ended up with something that looked more like a nightgown than a shirt. As a merch designer, I learned that sizing varies wildly between brands and even between different cuts within the same collection. That experience drove me to create this Sydney Sweeney merch sizing guide for 2026 - so you can order with confidence and get that perfect fit every time.
Understanding the Fit of Our Classic T-Shirts
Our classic t-shirts are designed with a relaxed, unisex fit. They are not slim-fit, but they also aren't baggy. The shoulders are set slightly wider to accommodate most body types, and the body length hits just below the waistband for most people. For a size medium, the chest measures 40 inches, length 28 inches, and sleeve length 8 inches (measured from center back).
What That Means for Your Size
If you usually wear a size small in women's tops, our small will give you a slightly boxier cut. Many fans prefer to size down for a more fitted look. For example, if you are between sizes, choose the smaller option for a closer fit and the larger for a relaxed silhouette. The fabric is 100% ring-spun cotton (for most designs), which has minimal shrinkage after washing if you follow care instructions.Fabric and Shrinkage
Our tees are pre-shrunk, but expect up to 3% shrinkage in length after the first wash. To preserve fit, wash in cold water and tumble dry low or hang dry. I recommend ordering your usual size unless you want a deliberately oversized look.Hoodie Sizing: Oversized vs. True Fit
Our hoodies come in two main styles: a classic zip-up and a pullover crewneck. The zip-up runs true to size, while the pullover is designed with an intentional oversized fit. For the pullover, a size medium has a chest of 44 inches and length of 28 inches, so it drapes loosely. The zip-up is more tailored.
Measuring the Oversized Fit
Many fans love the oversized pullover for lounging. If you want a true oversized look, order your usual size. For a more fitted appearance, go one size down. For example, a size small pullover fits like a medium in most brands. The hoodie is a 50/50 cotton-polyester blend, which means it holds its shape well and resists pilling.Zip-Up Hoodie Recommendations
The zip-up is great for layering. If you plan to wear it over a t-shirt, stick with your t-shirt size. If you want to layer a hoodie under a jacket, consider sizing down. The ribbed cuffs and hem keep their elasticity even after repeated wear.How to Measure Yourself for the Perfect Fit
Measurement guides are only as good as your ability to measure yourself correctly. Here is the method I use with my clients.
Step 1: Chest/Bust
Wrap a measuring tape around the fullest part of your chest, keeping it parallel to the floor. Keep one finger between the tape and your body for a comfortable fit. Do not pull tight.Step 2: Waist
Measure around your natural waistline, typically the narrowest part above your belly button. For most t-shirts, the waist measurement is less critical because the cut is straight, but for fitted tanks it matters.Step 3: Hips
For longer styles like hoodies or oversized t-shirts, measure around the widest part of your hips. This ensures the hem does not cling.Step 4: Sleeve Length
Bend your arm slightly and measure from the center of your back (where the shoulder seam would be) to the wrist bone. Our size chart includes sleeve length measured from center back, so this direct measurement helps.Step 5: Compare to Our Size Chart
Once you have these numbers, compare them to our size chart. For tees, prioritize chest measurement. For hoodies, also check length. Our chart is posted on each product page.International Size Conversions
Our primary sizing follows US standards. For international customers, here are general conversions. A US small corresponds to a UK 8-10, EU 36-38, and AU 8-10. Medium is UK 12, EU 40, AU 12. Large is UK 14-16, EU 42-44, AU 14-16. These are approximate because body proportions vary by region.
Why Conversions Can Be Tricky
International sizing is not standardized. A European size 40 can fit differently depending on the brand. I suggest using the exact measurements instead of relying solely on size labels. For example, our medium chest 40 inches matches a typical EU 40, but if you normally wear a US medium, stick with that regardless of your UK or EU size.Shipping Considerations
International shipping is available to select countries, with delivery times of 10-20 business days. Because print-on-demand means each item is made when ordered, returns for international orders can be more complex. So getting the size right the first time is especially important.Tips for Choosing the Right Size When in Doubt
If you are between sizes, lean toward the larger option. You can always cinch a baggy shirt with a knot or layer it. A shirt that is too tight will not be comfortable, and the print may distort.
Read Customer Reviews
Our product pages include reviews with fit comments. Many fans mention how a specific shirt fits. For instance, the "Euphoria" graphic tee runs slightly large, while the "Reality" collection t-shirts are true to size. I always check reviews for the specific item.Consider Your Wash Routine
Cotton items shrink more than poly blends. If you wash in hot water and dry on high, expect about 5% shrinkage. If you are between sizes and plan to tumble dry, go up a size. For hoodies, the cotton-poly blend minimizes shrinkage, so stick with your usual size.Common Mistakes to Avoid
- Ignoring the length measurement: A shirt that fits in the chest but is too short will be uncomfortable.
- Assuming women's sizing translates directly: Unisex cuts are different. Measure yourself.
- Not accounting for shrinkage: Even pre-shrunk cotton can shrink a bit. Order accordingly.
Pro Tips from the Community
Our community of fans has shared these hacks.
- Size up for layering: If you plan to wear a hoodie over a long-sleeve shirt, go one size up from your normal hoodie size.
- Test with a cheap tee: Not sure about unisex fit? Order a cheap similar tee to compare before buying your favorite design.
- Use a string method: No tape measure? Use a piece of string to measure, then lay it against a ruler.
- Check the product-specific guide: Some designs have special cuts. Read the description carefully.
Key Takeaways
- Always measure yourself using chest, waist, hip, and sleeve length.
- For t-shirts, our classic cut is relaxed. Size down for a fitted look, size up for oversized.
- Hoodies: zip-up runs true to size, pullover is intentionally oversized.
- International customers should rely on inch/cm measurements, not size labels.
- When in doubt, go with the larger size - you can always alter or layer.
FAQ
How do I know which size to order for a unisex t-shirt?
Measure your chest and compare to our size chart. Unisex cuts are based on men's sizing, so women typically need to size down from their usual women's size.
Will the shirt shrink after washing?
Our cotton tees are pre-shrunk but may shrink up to 3% in length. Wash cold and dry low to minimize shrinkage.
What is the difference between the zip-up and pullover hoodie fit?
The zip-up is designed true to size, while the pullover has an intentionally oversized fit. For the pullover, order your usual size for an oversized look or one size down for a more fitted style.
Can I return or exchange if the size is wrong?
Yes, we accept returns for unworn items within 30 days. Visit our Contact page to start the process. International returns may have shipping costs.
How do I measure sleeve length correctly?
Stand with arm slightly bent. Measure from the center back of your neck, across the shoulder, and down to your wrist bone. Use a flexible tape measure.
