Most measurements in our sizing chart (except collar size) are given for the garment, not the user’s body! We know that all men have a favourite t-shirt and we think it is easier to measure it, rather than wrapping yourselves with a tape. So grab yours, lay it flat and measure, ideally with a soft measuring tape. You should have enough reference to know what size fits you best… or just ask your better half to help you out. Either she’ll know better or you’d have someone to blame.
Just remember that BRO is an undershirt with some elasticity built in, so it should hug you and disappear under your outer layer, not hang loose on you.
Detailed instructions on how we took our measurements for the sizing chart are below. Feel free to follow.
