The two most common better-than-seamless swimsuit style requests we get are for thongs and full-coverage swim bottoms that fit like underwear. And sooooo…. Ta-da! Here’s Longshore, a style we’re really proud of. On the body, Longshore Full Coverage Bikini Bottom takes on an almost pin-up-y silhouette that we’re pretty obsessed with. Based on our core Compo Hipster Bikini Bottom style with added coverage, this is truly a bombshell of a dig-free swimsuit, Longshore hugs you close, flatters you, and stays right where it should with its full coverage bikini bottom fit. And thanks to our patent-pending edgeless bonded finish & comfy inner grip tape, we kicked the bulky elastics and seams to the curb, onewith style.    

📏 fit note: what size will flatter you most? Check your measurements against our chart here. If you're in-between sizes, you may want to size up in this style, as it's meant to be more of a skintight minishort!

• Garment imported from China
• Designed in USA, patent-pending
•  Soft, flexible inner grip strip to keep the suit secure
•  LATEX INFORMATION: we can not guarantee that the inner grip strip inside of our suits does not contain trace amounts of latex. Therefore, if you have a latex sensitivity or allergy, we recommend you exercising the same caution and sensibilities you would take in general when determining whether or not to use or wear a product that may contain latex.
•  Dig-free, elastic-free, edgeless smoothing laser-cut construction, just like your fave undies
•  80% recycled nylon 20% elastane
•  Hand wash only (rinsing in the shower is just fine), lay flat to dry

Now, we get it—everyone's unique, and the human body is more dynamic than any size chart could ever capture. That being said, our sizing quiz is the next best thing to actually trying on our suits in person 😉🔍

Disclaimer: While we strive to provide the most accurate sizing guidance possible, please note that individual fit preferences and proportions may (read: WILL) vary. If you have any further questions or concerns, our dedicated customer support team is always here to assist you...and, we offer 1 free courtesy exchange for domestic customers! Happy shopping! 🛍️💕

Size XXS is now available in select styles!

When sized and stretched properly, onewith will NOT dig in. Remember: you're a human being, and bodies are so much more dynamic than just numbers on a size chart. DM us if you want further guidance on best size!

NOTE: Do NOT expect our suits to be IDENTICAL to no-show underwear in fit. Do note that our suits do not have the same amount of stretchiness of standard no-show panty due to the inner grip strip & bonding.

Each product page features a fit note to help you choose your best size for that particular style if you find yourself in-between sizes 😊

Looking for cup sizes? We don't size by cup! Go with the measurement of the fullest part of your bust, and reference the Bust section of the chart. Or, shortcut alert 📣 order the same size you would for a camisole!

Some IRL size reference pics for you:

"can I just order a few sizes and styles and return what doesn't fit???"

please don't 🫠🫠🫠🫠 here's why.

⛔ Bracketing + high-quantity first orders are STRONGLY discouraged: while we understand the desire to find your best size(s) and styles, ordering multiple variants of a piece with the intention of returning those that do not fit/suit you creates inventory issues for us as a small business, and also compromises hygiene best practices. We encourage conscious consumerism by way of small, mindful first orders of 1-2 units. While we naturally love when you stock up on your fave swim once you know your best onewith size, please do so mindfully for our other customers' sake (that is, without the intention of returning extra sizes/styles). While this may be more permissible for an enterprise-level company, we ask that you consider how bracketing + large returns affect a small business, its customers, and the environment. Returns of 3 or more pieces/customer will be subject to a processing fee of $15.95 in addition to the return fee.
