All items are intended to be cut true-to-size (TTS). However, this doesn't mean all items will fit the same. Some items are intended to be oversized (Box Tee for example) while others may be more form-fitting. If there is ever a time that an item comes from the manufacturer and we feel it isn't running true-to-size, we'll add our recommendation for sizing up or down into the individual product description. Our models typically wear the same size in most items, however if they size up or down, you will notice in the description that we note the alternate size worn in ALL CAPS.
