Tell me more about the fit

Our Performance Innerwear is meant to fit snugly on the body. If you prefer a looser fit, we recommend sizing up. If it feels just a little tight and you aren't sure if the next size up would be better, we recommend wearing and washing it a few times to see if it breaks in to your liking before exchanging it for another size.

Will it stretch out?

Not really.  Our Performance Innerwear does give a bit with wear, but instead of becoming loose, it will mold to your body more over time.

For those who need some extra room—the Essential Busty Bra is a low-impact style, designed for C-cup sizes or larger, created with our signature Merino to keep you comfortable and funk-free all day. Best for light activities and everyday wear, our underwire-free, seamless design eliminates digging and rolling, while maximizing mobility. Convertible straps let you wear it straight or modify as a cross-back for additional support. Supportive without being restrictive, our Busty Bra reminds you how comfortable it feels to be in your own skin. If you’re between sizes, we recommend going one size up.

Bonus: Our ZQ, OEKO-TEX 100, and RWS certified GLDNspun™ Merino is also regenerative and sustainable. (which also means it is BPA free, PFAs Free, and toxic free).

Double Bonus: We hear it all the time… Our Busty Bra really feels like going braless—but with the gentle support you need.

Love this bra!

I love how comfortable this bra is! I even swam in it! I bought it because I like the way it looks for a sports bra, I'm not a busty gal but I ordered the small and it fits perfect!. I'm 5'4" and about 140 pounds.

Excellent

Obviously, it’s wool. It’s not going to feel super silky or soft when you put them on or when you feel with your fingers. But the magic happens once you’re wearing it! Once it’s on is the last time I think about it at all. It’s like I’m wearing nothing. So comfortable all day long.

mixed feelings - order up a size!

I love the idea of soft wool bras. I love natural materials and try to only wear natural materials, so when I heard about Branwyn I ordered a few items, different sizes and colors. At first I purchased a smaller size and was annoyed at how tight the waist band was. I then ordered up a size and this fit much better. Now I really like the Busty Bra. The bottom band is a little thick and I wish it was thinner but all in all I really like it. BIGGEST TAKE AWAY: ORDER UP ONE SIZE FOR COMFORT.

Took a few tries but I got the right size

Very nice bra once you get the right fit. I think the xl works for someone who is not as voluptuous as the model.

Want to love it, but...

This is a well-made, sturdy, and supportive bra. I want to really love it. But the band is too wide, and it rolls and rides up, creating a very uncomfortable experience. If it was just a bit thinner, it would be perfect.

Thank you so much for your thoughtful feedback! We’re so glad to hear you find the bra well-made and supportive, though we completely understand how frustrating it can be when the band doesn’t sit quite right. Since you mentioned the wider band rolling up, our Bralette might be a great option for you—it has a smaller band that some find more comfortable.

If you’d like any fit tips or additional support, feel free to reach out to us at info@branwyn.com
—we’d love to help. We’re always looking for ways to make our bras as comfortable as they are supportive!

MONEY BACK GUARANTEE FOR 14 DAYS

Not sure about wool?

Merino is super soft like cashmere!

We know you'll love it! But just in case you don't, we’ll give you a full refund.
