Omg. I’m so happy. I was skeptical but took a chance and so happy I did. And the fact that it is a Canadian brand is the cherry on top. The material is nice, soft and thick, but not too thick or compressive. Just enough to give you that confidence boost. The cups are fantastic. They don’t feel ridged but are much better than the ones they put in most swimwear and make the girls look amazing!! I’m 50, nursed two kids, menopausal and finally found a bathing suit that makes me feel and look like a beautiful woman without feeling uncomfortable or having to suck in my breath. It’s sooo comfortable. I put it on and no adjusting at all!!! Never stop making this suit. It’s the perfect one piece. Simple, sexy, well made and my breasts actually have room. Thanks so much Knix. You have a customer for life!! Will definitely buy more.

This is the best fitting swimsuit!! The best cut and it is seamless and doesn’t gouge into skin. The fabric is so soft and just lays smooth. I’m so excited to wear this. The color is true to the picture and is very berry
