Between sizes means measure twice and choose the layer you plan to wear. A Custom BYU Cougars Jersey in the larger cut works over a hoodie, while the buy byu cougars jersey in the smaller cut fits over a tee.
Check the chest, not the number on the label. A Bear Bachmeier BYU Cougars Jersey in medium sometimes fits like a large, and the LJ Martin BYU Cougars Jersey in a large sometimes fits like a medium.
Measure the chest. A custom piece in the larger cut fits over a hoodie, and the running back piece piece in the smaller cut fits over a tee. Try the shirt you plan to wear under, since the layer changes the size by a half.
Try the shirt underneath. A Jojo Phillips BYU Cougars Jersey layered over the garment you actually wear tells you the right size, and the Kyler Kasper BYU Cougars Jersey piece sized for a bare chest gets small fast when a sweater goes on.
Return the one that does not fit. A Legend Glasker BYU Cougars Jersey exchanged within the window costs a trip, and the same piece kept because it is close enough never gets worn.
Measure the chest, since the label lies more often than the tape. Try the shirt you plan to wear under, since the layer changes the size by a half. Return the one that does not fit, since a piece that is close enough never gets worn.

Write the measurement in the phone, since the next purchase goes faster with the number already saved. Try the shirt you plan to wear under, since the layer changes the size by a half.
