I'm torn between 3 or 4 stars for this review. I love the material and the design elements of this top -- the neckline is so flattering, the open back is extremely comfortable, and kudos to the design team for the built-in shelf bra. I can see myself wearing this to do Pilates (I'm also a teacher), but because of my bra size, definitely nothing high-impact. I am tall, 32F/G, middle-aged, athletic build. I *so* wish this was even 1" longer and had even .5" more material on the sides. The first time I wore this, I was constantly trying to pull it down to cover my waist. And after wearing it around the house for a bit before I went out, I decided I'd really be more comfortable wearing another sports bra underneath it to hold in my breasts a little better and to manage the side boob spillage. I still think this is very cute and comfy.
this top is EVERYTHING!! i wore it on a run the other day and it was so comfy and light. it’s so perfect with a pair of jeans too. the cut out in the back is my favorite part. definitely need this in every color 🩷
So stoked to finally own this tank and could not be more impressed with the quality, color, and style. Sized down to XS for a snug fit so I can be as active as possible without worrying about chest support. I'm a 34B and size 4 in most tops for reference. I officially need every color now. Please restock the brown in smaller sizes!!!
i love a tank with a built in bra and this one is 100
I got the oasis tank in Cabin & liked it so much I got Euphoria too. They're so comfortable and insanely flattering. I've worn them for everything from my long weekend runs to going on dates (and been complimented literally every time) ... hope more colors are added at some point!!
