Description
Step into that effortless, sun-drenched confidence with the Coastal Signal Underboob Bikini — a clean, minimal set designed to highlight your shape in the most natural, striking way. It’s the kind of underboob bikini that feels easy, light, and quietly bold from the moment you put it on.
The triangle top features a subtle underboob cut that creates a lifted, sculpted look while keeping the design soft and wearable. Thin halter straps tie at the neck and back, letting you adjust the fit exactly how you like it. The textured fabric adds a gentle dimension, giving the bikini a refined, elevated feel without overcomplicating the look.
The matching bottoms sit low on the hips with delicate side ties, creating that relaxed, leg-lengthening silhouette. The cut is minimal and flattering, designed for tanning, movement, and that effortless beach energy that feels natural and confident.
It’s the kind of set you reach for on repeat — simple, flattering, and made for long days in the sun.
• Underboob bikini design with a soft, sculpting cut
• Triangle top with adjustable halter and back ties
• Subtle textured fabric for a refined look
• Low-rise thong-style bottoms with side ties
• Minimal coverage for a clean, elongated silhouette
• Lightweight, stretchy fabric that feels soft on the skin
This piece is released in limited quantities and won’t be restocked. If it fits your vibe, now’s the moment to make it yours.

wasnt sure about the micro fit but it actually stays in place better than expected. the fabric has a nice sheen to it too
jess –
its really nice
Sienna –
literally the perfect tanning bikini. the strings are so tiny so you barely get any lines. i’ve already worn it three times this week and it’s holding up great in the chlorine
Chris Wells –

becky r –
kinda small on the top part but the color is gorgeous

okay so this is definitely for the brave lol. it’s very minimal but the way it ties is super flattering on the hips. 10/10
