Nautical Comfort

This sweater paired perfectly with a pair of jeans or leggings while I was visiting my in-laws at their waterfront in Maryland for the holidays. Comfy, timeless and TTS

Cozy Classic

This sweater was beyond comfortable and warm! I wore it for a trip to Chicago in the beginning of the fall and it was perfect for the weather. I styled it multiple ways and it fits true to size even with layers underneath. I would rent again.

Elevated cozy!

Its a classic striped sweater. Can't really go wrong! Has a boxy, oversized fit which was super flattering and cozy.

I LOVE this one. I’ll be wearing it all month and may not send it back. I’m partial to stripes and I love navy. Super cozy and soft. Some may argue too big but I like this one oversized. It’s going to be tough to part with.

Nice chunky fall sweater

I’m a size 14 on RTR and got an XL. Generally I wore this with a t shirt under it so it wouldn’t be too warm indoors. Really comfy and soft sweater. Really enjoying it

Unique detailing on front didn't work for me

Overall the sweater was very comfortable, but the v-shaped knit pattern on the front wasn't flattering on me. The sweater didn't sit right across my chest.

Strange Fit

The neck buckled in and the sleeve seams fell way far under my armpit. I don't know... It was all just very strange to me. I didn't end up wearing it at all.

Loved this sweater

This sweater was hard to return. Wore it with an oversized white shirt underneath. The neck was a little shorter than other t-necks and it fit me just great (I have a shorter neck). I was very tempted to buy this one. Would definitely order it again.
