Perfect tennis/golf outfit

I wore this to a tennis match and the colllar and length fit the bill perfectly! I got endless compliments. Since the fabric is knit it was not itchy and because it’s a polo cut you can wear a sports bra for max comfort! Highly recommend with the matching skirt!

Great top, tighter in the arms

This top fit me great in the bust, but was tight in the arms. If you have any sort of muscular arms I recommend sizing up!

Crop top that hits right

Beautiful top. Wear nude undergarments a must. Spring/Summer. Pair with a high waisted pant or short and it’s a winner.

Great Spring/Summer Top

Great color and great top! The armpit area is a bit tight so I am happy I went with the M. Also I am happy with the length, since I usually get really concerned about how short cropped top go.

It’s sheer so just be careful what bra you wear under it but it’s very cute and comfortable. Just the right amount of cropped for me.

Adorable spring crop

This was a great spring knit crop top- I wore it so many times with different things! I snagged it before the matching skirt was posted into RtR’s inventory but would love to order again as a set sometime. It is definitely a proper crop- so if you don’t like showing a little midriff I would avoid. So cutie!! 🥰 and comfy!

Must pair with skirt in set

Fabric doesn't give so going up a size didn't really help with how it falls oddly in some places but when paired with the skirt it looks perfect. If not getting the full set, I wouldn't recommend

Business Casual, But Make It Caribbean

The Derek Lam 10 Crosby x RTR collared knit top was my quiet flex at the conference — polished enough for lunch breaks and breakout sessions, but still carrying a little island energy with that perfect fringe detail. Paired with the matching bottom, it gave a subtle pop that felt professional and personal. It’s the kind of set that lets you show up smart, stylish, and still a little sun-kissed.

Wore this as the set & w other stuff!

Fit great, but I did have to take a straightener to the V-neck of the collar because it kept wanting to lay open on just one side. No lining so I wore a bralette underneath. Waist fit perfectly without being skin tight.

This is very cute

TTS and good quality- very cute and good with high waisted bottoms of any kind. I took off one star because if you are a lady with a larger bust this will quickly become a bar. I showed belly button for a guide on where it hits for a B cup

Cropped

Way more cropped than anticipated. Great quality, but didn't work for my figure.
