My husband likes to wear these sleeveless t shirts under his dress shirts to eliminate that "bicep" line created when regular t shirt are worn. Wearing these under white dress shirts especially makes the white "pop" and the look is overall more polished. These sleeveless T's are a good quality stable cotton (ie: sideseams don't twist and warp out of shape). Wider shoulder eliminates seeing the tank top outline of the more common tank style t shirts and just looks more professional. These have been very hard for me to find in stores but I will definitely be buying more here. I bought XL and my husband Is 6'1" and wears a 44 suit; fit is good, allows for a bit of shrinkage.
