Booo
Color: Pink, Size: Medium
Way too big for, I'm so bummed because this knit polo long sleeve shirt is way too big, even after I checked the size guide. It's a shame because the material feels pretty nice. I was really looking forward to wearing this. I can exchange it for a smaller size and that was too big. Lol

Nice Look
Color: White, Size: XX-Large
I love this sweater and everything about it. I purchased for family Christmas photos. I was worried it wouldn't look right or would fit too big. It fitted perfectly and gave me a very casual look. The color is white and not an off white. The quality is good and the fabric durable. It's stretchy so its flexible with your body movements. I highly recommend this sweater I'd you're looking for a light casual look. I recommend pairing with some jeans and a nice pair of boots.
