Great workout tank
Size: Small, Color: Cocoa
Great workout tank with built-in padding. Fits true to size, is comfortable and soft that hugs your form. Only reason I’m giving 4 stars is because the pads do get shifted around during washes, which is typical but frustrating. I air dry and haven’t had any issues with shrinking either.

Cute but NOT supportive
Size: X-Large, Color: Floral Pink Rose, Size: X-Large, Color: Floral Pink Rose
These are NOT “workout” tanks offering support. They have a removable cup sewn into the front of the shirt, similar to a bathing suit. If you have small (or gloriously high) boobs and want a shirt to hide your nipples, this is great. If you want something to actually give support, this is NOT it. There is no band to provide support. So if you have large or low breasts, don’t even try. You’ll have to wear a bra with it unless you want your boobs hanging below the sewn in cups. That being said, the material is great. It’s nice and thick with lots of stretch. The cut is also adorable. And I LOVE all the colors. I wish it just had a supportive band!

Comfy & cute! But low support
Size: X-Large, Color: Ocean Depths
This tank is super comfortable and I LOVE the color. The built-in bra is a little weird; I thought it was sewn in backwards but apparently not. It has low/medium support, bigger chested folks may not like this. Im a 36D and its right on the line for support where I can't decide about wearing this in public. I sized up and am glad I did; it fits well! Im 5'7" and 165lbs for reference.

Fantastic tank top
Size: Small, Color: Ocean Depths
This is a great tank top. I love that there is a inserted bra. I have read other reviews about the padding moving around during wash but that's really no big deal and easily put back into place. It's a super soft and well fitting shirt.
