The Black Heart Fit Guide

How to measure

Use a soft tape measure and measure directly against the body.

Triangle Bra: Use the same two measurements, underbust and full bust, and match them to the size chart below.


Between sizes

Silk is designed to contour comfortably to the body. If your measurements fall between sizes, we generally recommend choosing the larger size.


Triangle Bra

Choose your size using your underbust and full-bust measurements. Adjustable straps allow for a more personalized fit.

From Brennah, on fit.

“I’m a 32DD, and wear a Medium in our Silk Triangle Bra. It's the piece I reach for when I want something softer, lighter, and more effortless.”

Why Silk?


The first layer matters.

Naturally breathable and smooth against the skin, our lingerie is fully silk-lined to place silk where it belongs: closest to the body.

Loved by Lovies

Notes from the women who wear Black Heart.

I am obsessed, it’s one piece of silk that I can honestly say its already a favorite because of how it keeps my girls comfortable yet the touch of elegance takes it to another level! I love that its also a racerback!

JillieBlack Heart customer

One of my favorite things about this is how customizable the straps are. I’ve been able to switch up how I wear it depending on the outfit, and it always sits just right. Even with the adjustments, it still feels secure and well-structured, which really impressed me.

AnonymousBlack Heart customer

Package came very quickly, website was super easy to use! When I clicked on the bra it helped me complete the outfit in seconds (so that I didn’t have to find the pieces separately!) 10/10
