Understanding Fit
Fit preference can vary. These visual examples can help you understand the difference between a neater fit and a fit with a little more room, but your school-specific sizing guide should always be your starting point.
True to Size
A neat fit that follows the body without feeling too tight.
- Neat and polished
- Closer to the body
- Best for students who prefer a clean, tailored look
Room to Grow
A slightly more relaxed fit with extra room for movement and growth.
- Extra room through the body
- Comfortable for movement
- Helpful for fast-growing students
If your child is between sizes:
Recommended Size
- For shirts, polos, and sweaters, our sizing guidance generally allows for comfort and some room to grow.
- The recommended size in the school-specific sizing guide is usually the best starting point.
Check Bottoms Carefully
- For pants, shorts, kilts, skorts, tunics, and jumpers, measurements are more exact.
- Compare waist, hip, inseam, and length carefully before ordering.
Ask Before Sizing Down
- For a closer or more tailored fit, contact Customer Service before sizing down.
- This is especially helpful for blazers, tunics, kilts, and formal pants.
Important: Fit can vary by style. Always refer to your school’s specific sizing guides and product descriptions for the best results.
