I'm so glad to own these LuxeLift Tanks . I heeded all of the recommendations that say it's tight and must be upsized. This tank's built-in bra is so comfortable I don't take it off to sleep. I ordered 2 more. Some reviews said there was trouble with the armhole being too tight. That would have been concerning but I haven't found it to be so . The fabric is smooth and wide at the bra-strap on my shoulder and it just doesn't feel like there's anything there . I'm not going to be able to put on a bra after this . I've gained a size during covid-19. It's uncomfortable enough having big boobs. Having to strap on a wired torture device is too much. I'm done . I'm tired of wires and painful bra straps. I'll get as many of these as I need so that I never have to again. Super comfortable, super smooth, fits me perfectly, it's long enough to tuck in and leave no lines under clothing. Buy your size if it's a shapewear fit you're after. It will feel snug at first. Pull it on like pantyhose. It molds and form fits your body with wear. If you're like me and you want to live in it, using it even as a pajama layer, order it one size up. Step into bras and tanks that haven't got fasteners. Pulling it on is the only recommended option. That goes for all shapewear. Knix is better than any of the many, many other brands that I've bought. I'm really pleased to be dealing with a Canadian company during covid. I will spend my dollars in Canada every chance I get. Thank you, Knix people. You rock. My order shipped same day and Canada Post brought it in 5 business days.
