Wore this twice -- once with tux and once with shirt and tie. Offers a bit of lower back support for standing all night at a party. With tux, my shirt normally seems puff out as night goes on and cummerbund slides around. This is a gut issue. This shirt does not eliminate the gut (come on, it is only a shirt) but it does seem to smooth out and pull things a bit tighter. As someone else said, it is like when you suck in your gut for a picture. Makes my gut a bit flatter and that made all the difference. Cummerbund and shirt were perfect all night long. With the shirt and tie, I sang in a choir without any chest binding issues that might have inhibited excellent breathing. Actually felt good while singing and offered a bit of back and diaphragm support as well.

I had zero issues getting it on and off. Because it is a tank, the armpit openings were fine. Just pulled everything up and grabed back to pull it off. I like the style.

I plan to try wearing during golf for support. And I'll be looking for more at a discounted price. At $50+, it will not become an everyday undershirt.
