Product Description

It’s a work of art that makes you feel like one too. This bra-optional tank also smooths, contours and supports your shape, defining your figure in the most comfortable way. The go-braless smoothing and support comes from the Knix-exclusive ribbed fabric technology, so you don’t even need padding or a restrictive built-in bra. You’re going to want to wear it everyday, so you might want to grab a few!

    Soutien léger

    J'aurais préféré avec soutien intégré mais bien ajusté pour un petit support.

    Love the material

    Im happy with my purchase. Please note do size up as this tank runs small. But i like how it sucks you in. You can get away with not wearing a bra too.

    Itchy

    I loved the idea of this tank top, but after wearing it for an hour, I was uncomfortable. The size Medium was too snug around the torso. I think some people might be ok with the fit, but it was too tight for me. I also found it hot and itchy. I do have sensitive skin so will not be purchasing anything with this material again.

    I took the tag off so cannot return it. Will donate or offer to a friend.

    Very comfortable

    I love that I can wear this tank top with no bra and still be suported. It's comfortable. I liked the first one so much I bought more colours.

    Hot and a bit itchy

    It seems like a quality garment, but definitely not supportive enough for me to be comfortable wearing it outside the house. I also find it incredibly hot and a bit itchy. Maybe not the best choice for anyone with sensory sensitivity or peri/post menopausal body temp changes :)

    My fav new tank!

    Love this ribbed tank! The material is incredibly comfortable, feels supportive, and holds everything in without feeling too tight. It’s flattering, great quality, and perfect for wearing on its own or layering.
