Bellows is the ultimate in flattering swimwear, featuring a deep V plunge at the neckline, removable cups, and a confident cut to lengthen your legline. Like all of our swim, Bellows has a comfy grip strip at its inner edges to keep everything secure - even that gorgeous, deep neckline!
This suit truly goes beyond seamless swimwear for a totally edgeless swimsuit. So much so, in fact, that in addition to turning heads at the beach, you may just find yourself wearing this beauty as a supremely flattering bodysuit in your daily life. Our dig-free bonded construction and raw-cut edges make Bellows a total winner.
For more info, check out our size chart here which also includes torso measurements for Bellows.

It is terrible how much time I have spent staring at myself after putting this on! I got so many compliments too! The color is amazing and it gives like Baywatch vibes. Not only is it extremely flattering but it is also super comfortable. It’s versatile as well, I wore it as a bodysuit and it was absolutely perfect! The cleavage is on point. I’m obsessed! If it can work on my disproportionate figure (top heavy lol) it can work for anyone!
