Founded in 2007, Oiselle is the original boutique running apparel brand and the first to be built by and for women who run. Rooted in the belief that every woman is an athlete, we serve runners at every pace and every phase of their lives.
(P.S. It's Oiselle as in Mademoiselle.)
These have been my go-to bra for a few years now. Keeps the girls locked in and comfy for any high impact activity. They are very comfortable for all day wear and basically the only bra I wear now for trail running, hiking, mountain biking.
I have three and whenever they are in the laundry I'm sad -- this bra has the best combo of easy to get on, not too bulky for travel or hot weather, but great support and compression. No issues with bounce or chafing (for reference I have 34d and 32 dd). BUT very sad that on two of mine so far, after maybe six months or so, the clips attaching the elastic to the band in back have broken when I was taking it off. My makeshift fix is less comfy, alas.
I really do love the fit of this bra, however it holds moisture like CRAZY. I sweat a lot and it'll stay saturated for 6+hours, even when I've taken it off and hung it up. The cups are like sponges, and the whole bra gets heavy and saturated with whatever liquid touches it (sweat, rain, etc). Even when my quick drying shirts dry, the bra just rewets them and i end up with a big wet boob spots on my shirt.
Pretty please upgrade this bra, keep the fit the same, just find a way to make it dry and wick moisture better.
I have had 4 of these. Every single one has failed in the same way in about a year (see photo). That connector flexes and weakens, then snaps. Possibly make a version of this bra where there isn’t an option to cross the straps or wear straight to remove the need for these hooks? Make it more durable and add a pocket for us ladies who need support and to purchase band x cup size sports bras.

I have yet to sport a Oiselle item that disappoints- and the Boom Bra just upped the birds bar. Not sure how they managed to do it, but the Boom provides support allowing me to focus on the movement at hand (my running, and not my chest!) and NOT making me feel restricted, distracted, or self-conscious. I am a 32D in Brooks, and the sports bras I’d tried from Title Nine (along with my daily bras) and got this in the same size, and would say it is true to size. I cannot emphasize how ecstatic I am to have finally found something that doesn’t feel like I am stuffing my breasts into and praying I don’t get a bruised eye when I go out for a run or do a speed session. I will most definitely be adding additional colors of this item to have on hand. I’ve now done a couple 5 milers in this, and just did a 10 mile run today— and no chafing either! Head up, wings out… (*Boomtastic is what I titled my first run on Strava after wearing this for the first time. I was a little excited to say the least.)

I want to love this bra. It is almost great. The material is soft. I have a short torso and I like my girls strapped down and not much movement when I run. I have taken this bra on two shorter runs and unless i cross the adjustable part of the straps I just can't get enough compression from this bra. The straps don't go short enough. Sadly I paid $80 and it isn't a winner for anything other then the gym or cycling. It won't hold up even for 5K and I am looking for my new marathon bra.
My first run in this bra went went but I am concerned once it starts to stretch the straps won't adjust short enough for me. I have them crossed at the bottom to try to make them shorter. I have a big chest but a short torso so I have a really hard time finding a bra that really holds everything in place for long runs.
This bra had really good reviews online but after a couple runs, I think I’ll just accept defeat. It has good compression for chesty ladies, but it’s hard to adjust solo and doesnt have enough strap length for me with a longer torso. Also the material doesn’t have much give so it can feel too tight during an exercise when my torso is swollen from the exertion.
I run a lot and I never found a bra that was supportive and non restrictive at the same time. When I was training for a marathon the first time I chaffed raw from bad bras and had to wear two to avoid that. This bra delivers. I never write reviews but this is for the women who need a bra that actually feels nice and doesn’t rub you raw after an hour.
I love this sports bra so much. I’m a 36C and want everything held close to my body and tight. I have 4 of these and they do exactly that.
Love this bra - please add a pocket to the back for us ladies who need band/cup sized wear but want a place to put our phones. Please please please add a back phone pocket!
I love this bra more than I thought I would. I’m breastfeeding and this bra holds my boobs (36D-DD) beautifully. It doesn’t smoosh me or suffocate. I didn’t notice any unpleasant bouncing. No chaffing. Absolutely adore this bra.
It is not one I would say I could breastfeed in. I feed before I workout and then after, and just remove the bra when I’m done with my workout.
Took my new boom bra (36C) out for a 1.5 hr run and no chafing, total lock down, *without* feeling like I was suffocating. Amazing.
This fits me so well and has just the right amount of support. The band of this particular bra is slightly larger than a previous boom bra I bought in another color last year, but I’m able to wear it on the second hook with no issues.
I was a little nervous because with shipping issues I was only able to wear it after my taper had started before trying it for my first marathon. I was shocked and thrilled taking it off after the marathon because there was ZERO chafing. ZERO! (I did use some antichafing gel as well but that usually wears off for me around mile 10 and I didn't reapply). I do want to try a D instead of the DD recommended by their fit instructions, but the support is fine, just roomier than I like.
This is my go to bra for running and for everyday use. Love this bra. Holds me in place yet very comfortable. I have one in every color they make :) I am a 36 DD and love this bra for all of my runs..
This bra is extremely supportive with the perfect amount of compression. The molded cups might be too much for those running high milage in super hot weather. It's perfect for me. I love that it's 100% comfortable and can stand alone as a top with ample coverage for my comfort level. I bought 3! (50 yrs old/D Cup/TX) Thank you!!!
Tried it in a 5 mile run and i loved the support.
This is the bra I reach for, except when I want to bring my phone. Please add a phone pocket to one of your band and cup options for us larger busted/smaller torso ladies!
Very comfortable, fits perfectly, love the support, can do jumping jacks, burpees, etc. but wish it came in white.
Provides great support. Comfortable to wear. No problems with chafing. Difficult to put on. I've never mastered the skill of hooking my bra behind my back so I usually hook it in the front and then spin it around before putting on the shoulder straps. You can't do that with this bra so I have to have my husband hooking it for me.
I had to order 2 sizes up just to fit around my back. The shoulder straps are not long enough and cause extreme chafing where it rubs.
I’ve been looking for a replacement for my Brooks Juno bras and I think this one is a winner. It holds everything in place without chafing. I’ve run up to 7 miles in it with no problems although only in cool to cold conditions. I was really excited to find a bra that makes me feel secure!
As a 34C/D, I have always been in that middle ground where racerback sports bras fit me but were slightly uncomfortable. The small fits my ribs and gives me enough support but is too tight in my shoulders and is too compressive to be comfortable. Medium fits my chest but is too loose in the ribs. Enter the Boom bra. The clasp solves it all. I now have a bra that fits my ribs, provides support and isn't uncomfortable. Thank you Oiselle, I will be buying more.
This is the third Oiselle bra I have purchased. I started with the Queen, which I liked, but I lost weight and needed to go down a size. I then tried the Sisters Bra. I liked the way it felt and it rarely caused rub burns (marathon miles did cause some issues) but I didn't like the straps showing when I wore a tank top so I decided to try the Boom Bra and I love it so much that I just ordered another. I can't wait until more colors are available.
Believe everyone who says this is the closest thing to a Juno replacement - it truly is! I've been buying lightly used Junos off Poshmark ever since they were discontinued and this is legit the first bra I've tried in my search for a replacement that I can actually run in. It's also MUCH for comfortable than the Juno, which digs into my armpits.
That said, I've got one major issue with it - I'm a 38D in Oiselle bras and I absolutely despise the shape this bra puts the ladies into. They're high and wide and POINTY in places they've got no business being. Like it's impacting my ability to move my arms around in front of me and changing the fit of my shirts. I feel like Joan Harris from Mad Men. It's a similar shape to the Queen bra, but more dramatic. I reallyreallyreally don't like it and much prefer the minimizing effect of the Juno. Awkward bathroom selfies below for reference, I bet you can guess which is which.
In the end, I will have to be choosey about when to wear this bra depending on what shirt I want to wear, which is a huge, giant, disappointing bummer. It's so gosh dang comfy that even with the limited use case (I'm not often invited to mid-century themed cocktail parties), I'll keep it and use it when I can.
Thought I would never find a bra to replace my discontinued Skirt Sports bras (and before that Juno, but I date myself). Cycling seemed in my future. This hold is good with a little more give, but the sides and overall look is much, much better. Actually cute; its hefty price tag is well worth it! 34dd is my regular size and it works great. A running miracle!
Followed the sizing guidelines and ordered a 40D. Whoa. The cup size was WAY off. Band size was also a little loose, so I'm exchanging for my regular bra size (38D) and hoping that fits better. So careful when you follow their sizing guidelines.
Also, the padding was crinkled so when I did try on the bra, the crinkle showed through the fabric. Not cool. :( Not sure if it was damaged in transit since they ship in a plastic bag.
Will update if I can edit this when I get the smaller size bra. Because of sizing issue, have not gotten the chance to wear it yet.
I did get the 38D and it still fit terribly. Returned it and won't be trying any more.
This is the most supportive and comfortable sports bra I've ever had. I wear this in size 36DD and feel fully locked in running and biking. It is easy to put on too, which cannot be said for all high support sports bras.
