This was too short for me to comfortably wear as a dress, but it was SO cute to layer over all my outfits!

Threw this on like everyday

I threw this on like everyday working remote from home, so easy to wear. In those moments I did wear it as a dress since it was comfy but I like it much better open as a shirt with the sleeves rolled up. With denim or shorts... this oversized shirt look with shapewear underneath is v good

Team RTR Review

I really loved this top! It’s purposely oversized so I chose to wear it as a dress. I paired it with a belt to give it some shape and for style. It can also be worn as a beach cover or even open with some shorts would be really cute. I would go with your true size or size down depending if you decide to wear it open or close.

I probably wore this fifteen times!

I was SO close to buying this one. It did require ironing which is a downside. I recommend wearing spandex shorts underneath because it was quite short. I think the yellow color isn't as vibrant in person. Loved it!

Cute!

I ordered a larger size for this because that’s all that was available (size availability is really few and far between on RTR). It does fit big but I made it work and it’s really cute and comfortable

Absolutely love

This is such a great oversized dress that can also be worn as a top. I thought the length was perfect and covered all necessary places. Loved the relaxed but chic vibe. Definitely recommend wearing nude shorts or Spanx underneath just for comfort. Highly recommend!

Such a versatile dress! You can wear this as a dress, wear it open with denim, over a bathing suit as a coverup, and so many other ways. If you want a slimmer fit, I would recommend sizing down. I also would recommend wearing nude undergarments with this due to the light color! The lightweight and comfortable fit allows you to wear it all day long in the Summer!

Cute, simple

I was a little underwhelmed by this piece. Really love the idea of it- but it was actually pretty tough to style funny enough. And I think the color was wrong with my hair/ skin. But overall, really nice button down throw over.

Tried to size up and make this work for 3rd trimester. It worked okay but I think I could wear one of my husband’s shirts and achieve a better look.

LOVE the color...but don't love the rest

This is cute in theory and can be worked with. E.g. You can wear it open over some shorts and with a tank top. It's very oversized, I was drowning in it, but rolling up the sleeves helped. Could be a bit shorter, it say just about the knee. Overall, a bit meh.

Just Okay

I wanted to wear this to a day party as a dress with riding boots. It was much more stiff and bulky than I expected. The shoulders were pretty broad too. Would be better worn as a swimsuit cover up or open with jean shorts.

Surprisingly versatile

I almost returned it without wearing but then decided to take it on a vacation. Wore it a few times and really enjoyed it. Although not a fan of yellow, this one was a very pleasant shade. The fabric is soft to the touch but holds the shape very well and provides great airflow in hot humid weather while protecting from the strong sun. It was also in great shape. Would rent again.

beautiful butter yellow button-down - very long!

This was oversized and heavy, nice construction. It worked great for spring and given the natural fiber, it could also work for summer as a more substantial beach cover-up / shirt dress. Too long for me to wear shirt style, but styled like a "light trench-type coat over thin sleeveless sweater in matching yellow.

Perfect butter yellow- comfortable too. I would say at my height I don’t know that I would feel completely comfortable out and about as a dress, but with shorts underneath it was perfect.
