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.
I have waited so long for a pair of swim bottoms to fit like this and to actually be a flattering thong without making me feel like I’ve been tied up with butchers string and things popping out where they shouldn’t. I’m in between sizes right now and I’m losing weight pretty quickly, but it feels great to know that I can sit the waist up higher or lower depending on how I’m feeling and knowing it won’t slip
Thank you so much for your wonderful review, Jennifer! We're over the moon to hear our Penfield thong bikini bottom exceeded your expectations in both fit and coverage. It's always been our goal to provide swimwear that makes every body feel beautiful, confident, and comfortable. Enjoy your onewith :)
I have struggled for years to find a bathing suit bottom that fits my booty and larger thighs, and goes high enough so that I feel somewhat covered up. These bottoms fit like my comfiest underwear and don’t dig in like most other bathing suit brands do. I highly recommend the high waist thong for any curvy gurlies who are sick of unflattering bathing suit options digging into your butt and thighs. These are super sexy and super comfortable. 🔥🔥🔥
Hi Liz, thank you so much for your incredible review! We're thrilled to hear you've finally found the perfect, comfy-yet-sexy fit with our Penfield! We so appreciate you sharing and your recommendation for other women with a similar body type. Enjoy your onewith!
Excellent quality and fit. Will most definitely purchase more!
Hi Lacey, thank you so much for your amazing 5-star review! We're thrilled to hear the quality and fit of the Longshore exceeded your expectations. We can't wait to have you shop with us again soon!
This bottom is super comfortable and fits just like no show underwear!
Hi Heather, thank you so much for this review! We're so glad to hear you found the Penfield to fit just like your favorite no-show undies, and that it's super comfortable. Enjoy your onewith 🌊
