Not enough support for a my 34D frame.

[This review was collected as part of a promotion.] I'm 5'-3", 135 lbs, 34D. I purchased a medium and it barely held my girls together. Perhaps I bought the incorrect size and needed to size up, but the band wasn't thick enough so I returned it. I have other Merino wool bralettes that are more supportive.

I love this bra for travel and every day

[This review was collected as part of a promotion.] This is my third siren bra but not because they aren't well made- they are! My first (medium in a blush color) became a bit too small so I ordered a large in black. It was perfect so I just ordered this flesh tone one. I do wish the straps were wider, so it's 4.5 stars not 5. I can wear one day after day in hot, humid weather and always feel comfortable. They do get damp (no odor) when hiking in the mountains in hot weather but are dry by morning. On a long hiking day I used it and my queen briefs as a swimsuit and was as covered as any two piece I've owned. I never want to wear my other bras now and when I travel for 3-6 weeks, I wear one and pack one and that's one more than I really need.

I followed the sizing chart but the bra cup is too big

[This review was collected as part of a promotion.] I'm sad. I am a 36A. According to the size chart, I am an L. So I ordered not one but two size L bras. So much room in the cup area I feel I need to stuff my bra like I did in 8th grade. I should have bought a size Medium. Alas, I cannot return these items for a smaller size.

Nice bralette

[This review was collected as part of a promotion.] If you just want to soft, wool bra for wearing around the house, this is great. Its not very supportive, but it is very comfortable

Get it!

[This review was collected as part of a promotion.] This is now my 3rd Siren bra! They are really nice, especially for traveling. So comfortable and easy to care for. I usually get several wears before cleaning or simply airing out! Love natural fabric! I also truly appreciate having a pocket bra, for modesty. I don't want to give away all of my secrets! I have had one for over a year and it's still looking like new! I like to get another on sale, just to make sure I always have one available to wear.

A and maybe a B cup bra only

The material is comfortable but I have not worn it hiking yet. Unfortunatley my C cups are too voluptuous in this bra and they are smushed in the middle. Then today my right boob popped out of the cup and the cup was near my underarm. This is an A cup to a possible B cup bra only.

Fourth one I've bought

[This review was collected as part of a promotion.] Perfect for winter casual wear under flannel shirts and sweaters. Soft and comfortable. The light padding is nice to have.

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
