As someone with a larger bust, this is my favorite tank of all time! It's hard to find a tank that fits like a tank but still provides coverage and this one has it all. I ordered this in several different colors. I also like that it is not form fitting but has a bit of a roomy fit.

I love this for so many reasons, material is very soft. It is not a tight top, but it is not oversized or baggy either. It has perfect form without sticking to your body. The cut in the back is perfect because portions of your shoulders are exposed and you don't get too hot.

I bought this item for running outside in Florida and it’s been perfect for that! Light, breathable, sleeveless, and flattering. I recommend getting your regular size in this item for medium to dark colors and purchasing a size up for light colors as the material is very thin and you will see curves and clothing lines under the light colors (I ordered my regular size, medium, in this heathered blue color)

Always an UA fan and they never disappoint. Love the style and they’re really comfy and light. Got XS in this and still on the looser fit but it’s perfect (I wear AU 6/8 or XS in UA tanks). Great find in the clearance section as I’ve been looking for white UA tank tops.
This top is such a strange cut. I’m normally a 6/8/Xs but have larger boobs. Ordered an Xs and it’s really short in the front - I’m 5’1” tall. The material is suuuuuper stretchy and soft. But it’s the type that when it rides up, it will stay up. The cut around the bust is odd, but maybe because I’ve got bigger boobs. I’ll reorder a S or even a M to see, but I’m not paying £30 for it.
I love these tops and the Heatgear works for me i have the hsorts too and i love them.BUT looking closer at the top on the photo mine are dfferent they do not have gaps at the sides of the top and im unsure what else is different if the design can be totally different to the photo what else isnt right.I ordered all colours GREY PINK BLACK WHITE & I re ordered to ensure this was a mistake and it isnt. They came the same again no slits/gaps. I informed very but keep getting different people speaking to me so its stll unsolved. Why cant someone just get this sorted instead of saying re order it may be a problem with the item numbers. Starting to loose hope in VERY customer service I am having so many issues from collections not turning up to things not getting ... MoreI love these tops and the Heatgear works for me i have the hsorts too and i love them.BUT looking closer at the top on the photo mine are dfferent they do not have gaps at the sides of the top and im unsure what else is different if the design can be totally different to the photo what else isnt right.I ordered all colours GREY PINK BLACK WHITE & I re ordered to ensure this was a mistake and it isnt.

I would love to know what tops i have because they are not these
This is a nice colour and style. Does run quite large. I think it would be ok for the gym but the material is very soft and does not feel like it would be cool enough to run in.
I am normally wear a medium-sized top. I never have to try on a medium because it always fits. However, this top fits more like a large; every dimension of the top is larger than it should be, or at least in comparison to numerous other athletic labels. I could live with a top being larger than normal, but this top is not practical for any type of athletic use due to the deep neckline. I am not comfortable having the top lay so low on the front of my chest. So much skin exposure where it is not needed is a distraction for the wearer and anyone who might see the wearer. Sorry, but this top is going to Goodwill.
I order TWO of the knockout tanks. Both came in a few days apart but no worries. I really like these tanks and wanted these tanks but for some reason you all sent me not ONE but TWO WRONG SIZES.. I ordered a black in a size M and you sent me a size S. I ordered a navy in a size LG because you were sold out of M and I can get by with a LG; however, you send me a size XL. I’ve returned one. I will be returning the other. No sense in me keeping something that I CANNOT wear. I’m extremely disappointed.
I have this tank in several colors. It is really great for working out. The material has some stretch and is pretty thin so sometimes I layer two, especially the white one as you can see through it a little but if you are wearing a sports bra that works too. It makes for a a great running or jogging because of the lightweight moisture wicking fabric. I am 5’4” , 140 lbs (36D) and I can wear a Small because of how stretchy the shirt is for a fitted look and M for a more loose look. I would say M is the best fit though.
