Good cold day

Pros: nice casual option for a cold day, slimming fit, beautiful sleeve details. Cons: I have a sensitive skin and found the fabric a bit itchy. To remedy that, I had a cami under and wore it with tights. The dress runs a bit big, so I sized down after reading the reviews. XS was perfect.

Modest black sweater dress

If you’re looking for a modest sweater dress this is it. I did wear a cami underneath since it has a pretty deep V-neck. Like others mentioned the fit is more of a sheath style…fitted through legs and roomier in the middle. Works well if you carry weight in your mid section. I gave it 4 stars bc I felt that design made it slightly less flattering on me and the sleeves were slightly itchy (not terrible and ok for a few hrs) overall it’s a nice dress for a variety of occasions.

Weirdly shaped

I had such high hopes for this one and plan to wear it to a Friendsgiving event. I ended up going with a cheap Forever 21 dress instead. The waist was not at all fitted, and it was overall just bigger than it should’ve been as an extra small. It gave a frumpy appearance.

Cute dress- arms are slightly uncomfortable

I unfortunately didn’t get to wear this dress because of a last minute cancellation of plans BUT I did try it on. I’m usually a size 10 so I rented the large & XL Both fit fine, but I’d say the XL was slightly more comfortable in the sleeves. The “window panes” are a little scratchy and the XL was more loose so it was less bothersome. Overall, cute winter dress and I hope to rent it again someday.

Classic black sweater dress, dressed up

Takes the tradition black sweater dress to the next level with the paneling on the arms. The arm panels are a little itchy and I did feel like the dress was a tad pilly

Probably could’ve worn a large but was comfortable in the bigger size. Able to wear normal undergarments which is always a plus.

Okay

It’s a just okay sweater dress. Nothing too special about it, the fit is interesting. It hugs my hips great but very loose on the waist so it looks like it doesn’t fit right. The sleeves are also mesh and very itchy.
