Fits great but had to take pads out
Feels so secure and the fabric is so smooth! I'm a 32DDD and haven't found anything this easy to get into that was actually supportive in so long, much less a v neck! Loooove it!
For reference I am a short girly at 5’1”, weigh 275lb, usually wear a 1-2x depending on fabric and design, and usually about a 42DD. I am wearing a 3X in the onset bralette. I’ve only worn it once so far, to yoga, when I usually wear the uptight bra and I was SO happy and SO impressed!!! I have bottom-heavy breasts that have a bit of a mind of their own so they like to go on adventures and fail to loop me in lol. I of course came with a back up top just in case but the onset bralette was INCREDIBLE for yoga. I was comfortable and secure. I was worried the girls would move but NOPE! The little silicone strips kept them in place. I barely had to adjust at all, and when I did, it was the straps - not the girls! The thing I LOVE about this bralette is that it comes straight across the underarm, so all my side boob/underarm/back fat all get covered! It just makes me feel so much more comfortable and confident. I recommend this bralette SO HARD. And I absolutely need another one (or three). I want to note that I’ve never been a person who would show skin confidently, or was comfortable going to the gym or a fitness class without being completely covered because I was uncomfortable or because I couldn’t find products that would completely hold me in and I thought I would pop out everywhere. Since trying Arro, I’ve gone to every one of my yoga classes wearing just a bra and leggings. I feel comfortable, happy, secure, and more (semi)confident about how I look. If you’re a big girl who struggles with this, PLEASE give Arro a try. I don’t think there is a way you could regret it!
I’m always pleasantly surprised by ARRO’s products. I wear a 38F/85G bra size, and it holds everything in place in a way I never thought a bra could for a larger bust. It doesn’t feel tight or restrictive, but still gives great shape and support. It’s super comfortable, and moving around in it feels really natural. I think I’m definitely going to buy another one!
Bought for a 7 day road trip to have comfy clothing to wear. Very buttery soft material and absolutely love the grips inside the material. I do find the top is quite wide; great for coverage and support. I am quite small chested so a bit too much material and too wide for me personally but can make it work. The back straps adjust beautifully and are quality. The wide band is nice and doesnt roll over my stomach when I sit down The pads are thick and can be accessed by a slot in the material. Would recommend.
Love this bra and how it holds the tatas in place :)
Love the silicone in the cup area the girls don’t fall out, and the thicker band
Absolutely love this purple gingham pattern and the matching shorts! Super comfortable and supportive and everything stayed in place my whole workout! Despite how much I love it I hope they make a smaller cup size in the future. I had to cross the straps in the back and tighten them all the way to prevent gaping. For reference I’m a 30/32 C.
This bra is great. Better than I expected. I didn’t think it would contain my chest. But it’s way more supportive than I thought it would be. Not a full 100 go to grab for me but defenitly up there for me.
This is one of my favourite sports bras. The DV is very sexy, but it fits very well and the silicone lining on the boobs prevent it from falling down. I’ll definitely be ordering in another color. I got a large and I’m a 36 and it fits great.
I’ve owned a lot of leggings from here and I was very curious to try a bra. I’m around a 36 to 38D the band fits me really nice but the straps have to be fully tightened and I feel like I got a little bit of gaps just on the outer side but other than that absolutely love this product keeps the boobs in with the silicone liner
I absolutely love what you’re doing, and I’m so excited to support a female-owned and operated brand. The overall look and feel of the pieces is gorgeous, and I especially love how snatched everything feels. Even with a few small fit issues for me personally, I will 100% be reordering because I really love the concept and the results. I wore the bra all day because I loved the snatched look so much. For my body, I did find myself needing to readjust a lot throughout the day, as my breasts would shift over time. I also noticed that the straps unclasped several times after long wear, which made it a little tricky for all-day use for me, but I still loved how it looked and felt when everything was in place. The pants were great and very flattering. I did notice a bit of rolling at the top where there was no silicone area, but overall, I loved the fit and the shaping. I love supporting your brand. I’m excited to continue ordering and seeing how your designs evolve.
With the silicon strips there is no worry about popping out! ❤️❤️❤️
So comfy and fits great > I ordered an XL > only complaint was the hooks un hooking but after chatting with the owner I have it figured out !
Love this bra! Keeps my big chest in place. They do squish together in the middle a bit over time, but that’s expected….. but no spilling out! Love the leopard print!!
Very boobie-licious! lol easy to throw on when sitting in the sun or around the house but don’t think I’ll wear it in public I like but have a few cons about the bra. 1. Wish the straps would adjust further and STAY in place. Maybe adding silicone in the straps would help? I dunno 2. It’s more of a casual top and not a bra for the gym. I’m gonna order a size down next to see if that improves it but I doubt it
Hiked the hoodoos in +35 with no slip. I did have to adjust the strap all the way to the seam line, and due to that have some excess fabric/puckering in the cup. 5'3 210lbs wearing XL.
Love the fit. I also got the Weekender Sweater. My Arro closet is getting bigger.
Absolutely love this outfit!!! The waist band doesn't roll and you aren't spending all your time pulling them up because they are slipping!! The silicone strips in the bralette help keep it in place too! Only complaint is I missed out on getting the set in black 🤣 Great product, local small BC business & female owned! The trifecta!! Don't sleep on her products. Hands down better than any large corporation's product!!
This is incredible! I didn't think I would be a leopard print fan., but im obsessed! So flattering with the long band and silicone lined bra. Only critique is the straps were too long but I was able to adjust them further to fit perfect. Size small fits perfectly 35 bust, 32 underbust
I had to exchange my first purchase because it was too big in my chest area. When I received the new product, it was a better fit. My only complaint is that the band the goes on the rib area is a bit tight for my size but there is not in-between. For reference, I had originally ordered an XXL and exchanged for an XL.
I got compliments when I wore this to teach my class last week. The top was comfortable and stayed in place as promised.
Love the look but, I had to remove the padding as it was too much for my small bust.
Quality is top tier. Leopard print is beautiful. I wish the straps would shorten further without crossing them in the back. I'll have to sew a tuck in the underarm side boob area to tailor the fit to my body. Great for daily wear but not enough support for exercise. Arro are my new go to bras.
Love the style, but I am tall and I lean heavy chested so the straps don't work in criss-cross mode. Even in the longest position, they're constantly slipping out of the loops. Fits well in straight strap mode but has a little extra room in the under arm area that isn't there in criss cross mode.
such a great fit- my boobs dont look THIS good in any other sports bras!!!
I own 4 different on set bralettes. My first time ordering I got two large, the second I got XL. The large is good for relaxing and sunning but for everyday wear and movement I prefer the XL for more coverage. In the other bra styles offered by arro I prefer to wear a large but as a bustier girl I feel more secure in the XL. My only complaint is the clips, however this can be resolved by crossing the straps.
This bralette is everything that I have been looking for for so so long. As a person with a larger, bottom heavy chest finding bralettes that the girls can't escape from has been a challenge. The onset bralette keeps them contained through even a prolonged down dog. I'm in love and will need to have one in every color.
Love this! The only thing I found was I am larger chested but I found I could size down to a medium for a more snug fit. The Large does fit nice but I find with having a smaller back the Medium would probably work better
Comfortable coverage. Band does feel a bit to wide for my frame but it does contour the body well.
Love the colour and support during work outs!
So so comfortable even on my 38J chest
You need to offer sizing for different cup sizes NOT just a band based off ie. XS-XL…without that it doesn’t fit correctly…
I would love to leave a photo or video for you but I’m not comfortable enough with my self yet to post photos or videos. Love the fabric had a few issues with the clasp in the back, but customer service was great and told me how to fix the issue
Absolutely love this bra. I have been struggling finding bra's that are not only comfortable but support and don't ride up. This is the bra! The only thing, I found that I could go 1 size down then what the site said I should be. Will 100% be purchasing more!
I really wanted to like this but the very first wear the straps (which were adjusted to fit well) kept coming undone. Literally in the grocery store with one tit out.
It’s so comfy and so soft! I needed to add a stitch in the middle for my own comfort level of boob exposure but that is my own self confidence!
Love this sports bra. No more uno-boob. Only issue I have is the band keeps rolling up in front.
Fits great. True to size. Very comfortable.
Super cute ! If you dont have big boobs I would size down if you could in the band. Totally wearable and still love it
