onewith = 2 layers of normal swimwear fabric, just like any other swimwear. people tend to think our swim is either 1 layer of fabric, and/or super thin, like no-show undies. that is not true! again, our swim has 2 layers of fabric. It's just bonded together, not sewn with tight seams, which gives it a sleeker appearance that people may read as "thin." While we can't guarantee our suits are frontal-wedgie-free, so-to-speak as every person's anatomy is different, we can say that there is no reason why our suits would cause 🐪toe more than any other swimwear.

yes, all of our bikini tops + one pieces have removable bust cups that you can leave in, or take out!

we get it, the itch to get your swim that doesn't dig in ASAP is real! luckily, we do offer an Express shipping option if you do need it ASAP. otherwise, we offer free standard shipping on US orders over $85. all orders with standard shipping ship from our Connecticut, USA warehouse within 2-5 business days of receiving your order.

ALL onewith suits feature our inner grip strip, which keeps the suits secure without the use of tight seams or elastic that digs. the inner grip strip is super soft and flexible.
