Super baggy
Size: Medium, Color: White
I’m Taking away one star for the bagginess and length of the top
It’s super long
I kept the top because the fabric is super soft, drapes nicely in the front, and can be used to wear under a blazer or on a beach
Fabric has been washed and dried several times and has held up nicely
Some minor wrinkles

Nice and soft tank tops!
Like the tank tops (3); they wash and dry well and did not loose their shape. Wish arm holes were a bit smaller. Purchased these to wear when I exercise. They also work really well under a long sleeve shirt for purposes of layering in cold weather. Material is very soft to the body.

Fabric was definitely not what was expected.
Size: Medium, Color: White
It was thick and very stretchy. It didn't feel like 90% cotton felt more like 90% spandex. It also was deceiving in the picture. the hem was straight across rather than tapered like I was hoping. IDK, maybe they sent the wrong one. Regardless it is going back.
