Size Guide

Use the chart below to find the size that best fits you. The measurements listed represent the ideal dimensions for each size.

Example: if your bust measures 36.22”, the Medium size will offer the perfect fit.

Some of our pieces — such as kaftans — are one size fits all. In those cases, use the Medium measurements as a reference to check whether the item will suit you comfortably.

Our bikinis are thoughtfully designed to celebrate modern femininity and elegance, featuring our signature Brazilian Cut.

Please note: this chart serves as a general guide, and slight variations in measurements may occur depending on the style.

Refined texture, timeless lines, and a fit you can make entirely your own.

The Siena Textured Bikini Set reimagines the classic Brazilian triangle bikini with subtle texture, delicate gold-tone accents, and adjustable ties designed to flatter your natural silhouette.

The sliding triangle top allows you to customize the coverage across the bust, while the halter neck and back ties provide a secure, personalized fit. The coordinating low-rise bottom features adjustable side ties, making it easy to position higher or lower on the hips depending on your preferred look.

Available in soft Butter Cream and vibrant Poppy Red, Siena transitions effortlessly from relaxed poolside mornings to beach clubs, yacht days, and warm-weather escapes.

I chose Siena because it turns a classic triangle bikini into something much more refined. The texture and gold details elevate the simplicity of the silhouette, while the adjustable ties make the fit incredibly versatile.

The bottom has a Brazilian cut with minimal-to-moderate back coverage.

Can the bottom be worn higher on the hips?
Yes. The side ties allow you to adjust the rise and wear it lower or slightly higher on the hips.

I was a little nervous ordering swimwear online, but Amazonia Beachwear completely exceeded my expectations. The bikini fits beautifully, the fabric feels high quality, and the design is both stylish and comfortable. I wore it all weekend at the beach and it held its shape perfectly. I’ve already recommended it to several friends!
