- Beach Club Chic: Layer a sheer white kaftan or kimono over the swimsuit, add wedge espadrilles, and accessorize with layered gold necklaces and a woven crossbody bag. Perfect for transitioning from beach to lunch.
- Yacht Day Ready: Pair with high-waisted white linen shorts when not in the water, add nautical-striped espadrilles, and accessorize with a silk scarf tied in your hair and oversized cat-eye sunglasses.
- Tropical Vacation: Style with a colorful sarong tied at the waist, flat sandals, and tropical-print kimono. Add a flower hair clip and shell jewelry for that island goddess vibe.

Styling Q&A
- Q: How long does shipping take?
- A: This item qualifies for standard delivery and typically arrives in 7-12 business days within the USA.
- Q: Is the V-neck too revealing? Can I adjust it?
- A: The V-neck is designed to be eye-catching but not overly revealing. The adjustable straps allow you to control the depth—tighten them to raise the neckline or loosen for a deeper V. You're in complete control of your comfort level.
- Q: Will this provide enough support for larger busts?
- A: Yes! The built-in structure and fully lined design provide good support. The high-elasticity fabric offers gentle compression, and the adjustable straps let you customize the fit. For extra support, consider sizing up for a less constricting fit.
- Q: How does the "detachable" feature work?
- A: This swimsuit includes detachable elements (such as removable straps or accessories) that allow you to customize the look. Check the specific style you receive for its unique detachable components.
- Q: Can I wear a regular bra underneath?
- A: We don't recommend it—the built-in support and lining are designed to be worn without a bra. Adding one would create visible lines and reduce the sleek appearance. The swimsuit provides sufficient support on its own.
- Q: Will the color fade after swimming in chlorine or saltwater?
- A: The durable fabric is designed to resist fading from chlorine and saltwater. However, always rinse thoroughly with fresh water after each use and follow care instructions to maintain the vibrant color and fabric elasticity.
- Q: Is this appropriate for actual swimming or just lounging?
- A: Both! While it's absolutely stunning for poolside glamour, the supportive fit, high elasticity, and secure straps make it functional for swimming, water aerobics, or beach sports. You can be active without worrying about wardrobe malfunctions.
- Q: How do I determine if I should size up one or two sizes?
- A: If you're on the smaller end of your US size or prefer a fitted look, size up one. If you're between sizes, have a larger bust, or want more comfortable coverage, size up two. Remember, swimwear should never feel restrictive.
