Would love in more colors
Love the style and fit of this dress. The pockets are a much needed and it's my go to dress for everything: with sandals, with leggings, with boots, dressed up or just a quick throw on to run errands. Would love to have more colors. I'm 5'3 and it's knee length for me. I have broad shoulders and am a bit of a pear and this fits great. Please make another color!
Love this dress!
I bought this at the retail store - luckily because if I saw the photo with this poor model styled in the pink jacket with the crazy ascot there's no way in h*** I would have purchased it! Dress looks fantastic with leggings. Easy to dress it up with a flashy necklace or earrings for work. Great fabric. Runs big.
I’m in love
This dress is my go to...& I don’t even like the color. It’s SO comfy & easy. I get compliments often on it. REI pls make more colors!!! I’d buy every single option. BTW I’m a XS in REI but the S looked better on me.
super comfy and stylish
i only just got this dress yesterday, but i love the look and feel, as well as the color. Comfy but stylish. My only complaint is that the price seems a little steep.
Dress to wear for the apocalypse!
Very substantial. Kinda heavyweight, but thats good for wearing to my work. Good pockets and very roomy, I got the small as thats what was left at the time, but fits well, I normally would wear a medium. Good pocket situation. Theres no stretch though. Kinda stiff, but should soften up with washings. Perfectly utilitarian and will be great to wear to work this spring summer.
