All our styles are sized slightly differently due to the fit, therefore we recommend using our comprehensive size charts when choosing the right fit, which are available for each style. Please note, as with all clothing manufacturing, there is a tolerance. Although we do our best to avoid inconsistency, all items cannot be exactly the same. Please let us know if you are unhappy with the sizing of an item, as although it may not be considered faulty, if the item is unworn and returned within 14 days of receiving your order, we may be able to locate a suitable replacement. Please note, due to the nature of the fabric on our OB-T, OB-V and Terry polos, our tolerance must be higher than usual.
