LOVE. Ordering more colors.
Size: Medium, Color: Porpoise, Size: Medium, Color: Porpoise
I absolutely LOVE this sweater. This sweater is so flattering and comfortable. Great quality and the material is cozy and soft. I will be ordering this in more colors for sure! I just got it today but I know this will be my go to this season for lounging as well as being out and about. It could easily be dressed up or down and I love the Porpoise color I got (see photos). Originally I thought this came in a set but I still thinks its worth the price for just the sweater and I plan to order the shorts anyway. I got the medium and it fit true to size and so flattering. I am 5ft 2 and about 140lbs being heavier in my legs/hips. I generally wear a small/medium on top depending on the style and a large/XL on bottom. Definitely will be getting more colors!!

beautiful Perfect Sweater! Highly Recommend!
Size: 3X, Color: Zephyr Pink
Gorgeous color. Soft and snuggly. Cool enough in summer for office wear. My office sometimes gets cold even in the summer and this sweater is perfect. I wear it with brown slacks and it looks very professional but could be dressed down for casual affairs. The cut is generous and maybe even runs a little large however, I like the loose fit. I still can't get over the neutral pink color. It is just amazing and was a real steal as it was on sale when I ordered it!

Stylish and comfortable
Size: 3X, Color: Porpoise
I love the slit in the back, it elevates the sweater well. It’s comfortable and made out of a thick, quality material. The only downside is that the sleeves are quite long and don’t roll up well. Otherwise I love it!

Cute but pills
Size: 3X, Color: Chocolate
Runs a little big. I’m good with that. The style and brown color are great! I love the wide sleeves. The material is very soft and cozy…but I wore it once for 3 hours and the sides and stomach area pilled. I am disappointed. I am going to hand wash it and see what it looks like. I may need to return it.
