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.

Good but not great

I’d been wanting a merino bralette for a while and Branwyn had really good reviews. I’m a 34b, and based on the sizing, I went with medium. I got both black and tan. When they first arrived, they were very tight across my ribs and I had to stretch them out. Over time they got more comfortable but I wouldn’t say that I forget I’m wearing them. They were a little itchy at first but have softened up over time. The band does seem to rise up a bit and I find myself pulling it down. The “cups” are also not very big, even on a chest that isn’t very big. Overall, I like the merino and they will be good for travel. I don’t like the pattern on the tan bra and wish it was solid. I’m going to keep the bralettes because I like them more than I don’t, but I don’t think they’re perfect, particularly for the price.

Cozy

When I first put the bralette on, I thought to myself that it wasn’t soft but more on the itchy side then I told myself I was gonna wear it for one day and I stopped noticing the itchiness and it’s now super comfortable and soft. I ordered my reg size and I ordered 1 size up in the undies and they both fit perfect.

So far so good!

Firstly, this was a LOOOT for me to spend on bras (the welcome discount helped) :) I think they were worth it though to add to my undergarment wardrobe. I also quite wearing formal bras years ago. Basically just weddings and events, lol.

I have pretty small tatas (a/aa) and this still gives a nice shape. I do tend to still stick foam pads in it for everyday, which I guess defeats the wool bit, but looks nicer under certain shirts. Anyway, I really enjoy these bralettes and bought in nude and black. And I don't need a whole drawer since they wear quite a few times before needing a wash!

The low scoop neck and the floral pattern weaved in in a nice, feminine touch for an otherwise "unsexy" type of undergarment.

I can't say there is anything wrong with this bralette! I do wish that it were a bit more "longline" so the band doesn't ride up, but that's more of a personal preference. I would LOVE if they would make more of a longline bra/tank type undershirt! I used to wear the PACT ribbed racerback tanks and no bra and loved them, but they're a bit thick and also stay damp when you get sweaty.

I wish these came in more lovely colors, but also appreciate their focus on sustainability.

I got started on wool undies this year because regular undies and bras on my motorcycle were gross and....causing problems.

I've had them a few months and only washed less than a dozen times. I machine wash in a high quality garment bag and then hang dry and they seem to be holding up.

I'm a bit concerned about the type of detergent and it seems hard to find a reliable wool-friendly detergent that is also scent free and actually works. I tried the Dirty Labs one and was NOT impressed (especially for undies). So I went back to my Seventh Generation clean n clear, but I think the enzymes might damage the wool over time. Anyway, that's something to consider. (Branwyn support please feel free to chime in here!)

Wool bra. I get it 🥹

The fact that I can wear this bra over and over and not worry about odor or bacteria just blows my mind. I've worn it two times already and it is soft. I washed it just for good measure but it was soft even before I washed it. This is a wonderful investment and I cannot wait to add more to my collection.

First Wool Bra

I bought this to test as I will be one bag traveling this winter. I’m two days in and I really like how it feels. No itch. The band on the bottom does bunch up but it doesn’t feel uncomfortable, sometimes I can’t feel it. It’s very soft. I’m likely going to buy more.

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.
