I ordered this to go under a short sleeved Vietnamese blouse. I'm usually cold so knew I needed an undershirt.
And yellow was the color I needed. Not pale yellow, not orange yellow. But yellow yellow. Couldn't find yellow anywhere but online.
Shirt works perfect under the blouse.

It's way more comfortable than I expected. It's soft and it doesn't ride in my underarms. I hate shirts that ride in my armpits.
It's a thinner material.
