Margot Butterfly G-String in French Blu

A little stripe, a little ruffle, and absolutely nothing in the way.

The Margot Butterfly G-String in French Blu by Only Hearts is the barely-there companion to the Margot Cadeau set. Classic navy-and-white seersucker stripe meets a delicate ruffle trim in a g-string silhouette that's as pretty as it is minimal. Crafted from 100% OEKO-TEX® Standard 100 certified cotton — every raw material, every dye, free of harmful substances to your body and the environment.

Why she'll love it

• Delicate ruffle trim for a soft, feminine finish
• Barely-there g-string silhouette — seamless under everything
• Lightweight seersucker cotton that breathes beautifully
• OEKO-TEX® Standard 100 certified — clean materials, clean conscience
• Pairs perfectly with the Margot Cadeau Bralette for a complete set

Fit & Feel

100% cotton seersucker — soft, breathable, and lightweight against the skin. The ruffle trim adds a romantic touch without bulk. A minimal, low-profile fit designed to disappear under clothing while still feeling special.

What makes it different

Only Hearts has been crafting thoughtful intimates in New York City for decades. The Margot Butterfly is made with OEKO-TEX® Standard 100 certified cotton, meaning every fiber — from raw material to finished dye — has been tested and verified free of harmful substances. Wear it well, wear it clean.

How to wear it

Style with the Margot Cadeau Bralette for a coordinated French Blu set, or wear solo under high-waisted denim or a summer dress for a seamless, barely-there feel.

Fit Note

True to size. The g-string silhouette is designed to sit low on the hip with minimal coverage at the back.
