FAITHFULL Sierra Bikini Bottom

Product Insights & Style Tips

The FAITHFULL Sierra Bikini Bottom in Brown feels like a sunlit mood board you can actually wear. The fabric lives in a lightweight swimwear weight, a recycled Econyl polyamide mix (78%) with 22% elastane, so it moves with you and holds its line as you wander between shorelines. The earthy brown grounds the look, a quiet nod to Faithfull’s sun-drenched, bohemian spirit.

Sold as a single bottom in a full XS–XL range, it invites easy mix-and-match with any Faithfull top. The elastane keeps the fit flexible enough to glide with movement, while the 78/22 blend holds its shape for beach days and poolside explorations. Not sold as a set, so you can build your own pairing—slip it on with a linen shirt over a sun-drenched supper, or wear it with a lightweight cover-up as you stroll along the boardwalk. Hand wash.

Faithfull’s DNA—Scandinavia meets Australia—lives in this piece: pared-back, bohemian ease, hand-sewn and hand-printed touches across the collection, and a sun-soaked spirit that travels from beaches to boulevards. The Sierra bottom is the sort of staple that pairs with beaded kaftans or a crisp white shirt tied at the waist, keeping the mood laid-back yet polished wherever the day takes you.
