Cute but very warm

Very cute sweater but a little thick for Texas winter! The neck of the turtleneck is also pretty snug

Great sweater

Got with the matching skirt. It is sliightly itchy but I wore a shirt under and it was really fine - I’m easily overstimulated, so I would tell you if I was ripping it off at the end of the day. The only size available was small and I was worried it would be big but it was fine, especially if I tucked it slightly into the waistband of the skirt. Super cute outfit for fall, got a lot of compliments and felt put together.

Elegant but so very easy to throw on. Wore the set on a girls’ trip to Falling Water, and it was perfect for sightseeing and then rolling into dinner.

Cute but itchy

Cute turtleneck sweater! I was able to wear with multiple different looks. It was a bit scratchy on the inside but I wore an undershirt with it and didnt bother me so much!

Like walking around in a cashmere blanket

This was so soft and comfortable! I don’t want to take it off. I rented the set and it was a little difficult to style for my small frame. This sweater was definitely oversized and I wore it a few times with leather leggings and jeans. The fit isn’t exactly flattering - it is overall thick, wide, and long, but it is a stunning knit (looked and felt like cashmere? Can’t remember if it was) and many people wanted to touch it. It radiated coziness.

Just perfect

So soft and cushy, and a beautiful color. It’s a great oversized shape but it’s doesn’t run super large - I might rent it again in a small (and then maybe buy it). The neck is a bit snug and the sleeves slightly short - would be petite friendly.

Incredible Set!

Wore this set for a holiday party and received so many compliments! It’s so warm and cozy - I will say it is a bit itchy, but if you wear layers underneath it’s totally fine. Amazing fit!

SUPER Warm

This looked amazing and IMO expensive. I felt super classy. I live in FL and it ended up being WAY too warm - I thought I might pass out. If you experience true winter, this is perfect for you! True to size. A tad itchy, so I’d wear a shirt underneath. Not sure I’d wear this without the skirt because it doesn’t do much for your figure.

Basic, good as a set

I wore this with the coordinating skirt and liked the outfit. Fit is oversized and longer. I wish it was a bit softer, I wore a tank underneath but the neck was a tad itchy

Alpaca was super itchy for me!

Thought this set was giving ~quiet luxury~ but I found it SO itchy especially at the neck. I could not keep it on my bare skin for longer than 30 mins. It was only available in a size too big for me and wish I had gotten my regular size.

If you want an oversized look and have bigger hips, size up w/ the top!

Love this set— perfect for everyday fall/ winter events and warm enough to wear in 40-50 degree weather without a jacket!

Soft neutral with great texture

This Rails top is the perfect beige color. The texture is beautiful and gives it that cozy, elevated feel. It is a bit scratchy, but wearing an undershirt makes it totally fine. I do wish the collar was either a full turtleneck or a crew since the mini mock neck felt a little in-between, but it still looked great styled. It’s warm and ideal for the cooler side of the season

Cute but itchy

Super cute and the color was perfect. Was hoping this was a versatile option to keep for a while, but the discomfort made it hard to enjoy for long. I found it quite itchy even when wearing a shirt underneath. If you have sensitive skin, this may not be the best choice.
