Size up!

[This review was collected as part of a promotion.] Solid bralette, but it runs small! I'm normally a 36A, or a size S in most sports bras, but I listened to the reviews and ordered a Med. So glad I did! The band is even a bit tight!

I love these bras!

[This review was collected as part of a promotion.] Never get stinky, great fit, look cute, no itch! I know it will stretch out as my other one did. I'm technically an XL for rib girth but an A cup

Love it

[This review was collected as part of a promotion.] I absolutely love this bra. I did order a size up (S) from my usual (XS) and the band fits perfectly (for a 32B). It's super breathable, not itchy, and has a nice level of support for a light bra. Ultimately what matters most to me is that it's primarily made of natural wool and I've worn it skiing, hiking, and just out and about/around the house and it's been perfect in all situations. Highly recommend!

Definitely buying another one in the future!

[This review was collected as part of a promotion.] Very happy with this bra! I was worried about fit from other reviews about being too small from others but it fits great for me after taking my measurements and comparing to the chart for sizing. I'm used to a looser/more relaxed fit and the one I chose is tighter. I like it for when I'm working out. The next one I get, I'll go up a size for a looser fit so it's comparable to what I normally wear.

The only bra I wear!

[This review was collected as part of a promotion.] This is my second Siren bra and I love it! The fit is very comfortable and I wear it daily. I can wear it many days before it needs a wash, I just hang it up to air out each night.

Love it!

[This review was collected as part of a promotion.] Super comfy! I'm always a S in bras, and a S would have fit well/a little snug if I wasn't pregnant. I kept the S and ordered a M and for me that was a perfect maternity fit! If in doubt size up :)

Getting more!

[This review was collected as part of a promotion.] This is the first wool bra that fits my small chest. I am in love. I hope it lasts longer than some reviewers have mentioned, but in the meantime, I am finally comfortable. I ordered a large and an extra large. The extra large went to my daughter, who took out the inserts. I kept my inserts (they're a bit fiddly, but they make t-shirts look smooth) and I will be ordering more of these bras soon.
