    Love this but...

    This dress was my go-to for the beginning of the summer, but after a couple of washes, the zipper continually stuck. I was unable to zip it myself due to it catching about halfway up. Eventually it wouldn't zip past the middle, making it useless. So sad because I loved the style and the fit.

    Size up and leave zipper zipped.

    This dress looks great once you figure out the best way to use it. It’s highly unlikely you’ll be able to zip it yourself. Size up, make sure the zipper stays zipped, and pull it up. If they redesign this dress with a side zipper I’d buy it again in a different color. It really does look super cute!! But the sizing is off and the zipper is terrible. Knix are great with exchanges/refunds, of course, but if you get it on sale, you won’t be able to get an exchange.

    Perfect summer dress

    I bought this to wear to an outdoor engagement party in 30+ degree weather with high humidity. It was perfect! I sat in balsamic reduction glaze… sticky… stuff at one point in the night. I snuck into the bathroom, dabbed the spot with some soap and water, and it dried within minutes! No stain!

    So good except the side seam

    I love this dress so much, I want to give it 5 stars because it's so comfy and versatile. It can be dressed up or down easily. My only gripe is the side seam that rests beside my arm doesn't lay flat so after just one evening my arm got chafed and irritated. Not sure if this is the way it's designed or something went wrong on my dress.

    Zipper broke after first wear

    Loved the cut of this dress, it was so flattering

    Wish it had the easy pull down shorts, it made zipping complicated

    I had issues with my dress and Knix was amazing about it. Hoping it gets redesigned

    Love it, but…

    I love this dress especially because it actually fits my large breasts without a bra and holds them in. The issue is that the zipper constantly gets stuck about halfway up. It makes it difficult to zip on my own.

    Love this dress!

    I love that you don't need to wear a bra or shorts with this dress because it's all built in. It feels super cute and elegant with the high neck and little straps

    Cute but difficult zipper!

    For some reason I assumed the zipper would be on the side but it is on the back and I find it really hard to zip up on my own, which makes this difficult to wear in public in case I need to go to the bathroom! The dress looks really cute on and it’s comfortable, and maybe my arms are short or something, but without my boyfriend, this feels impossible to zip on my own!

    The zipper broke the second time I went to wear it. A lot of money for a onr time wear 👎
