Fun Christmas Sweatshirt
Color: 02 Green, Size: Large
I really like this sweatshirt. It was listed as men's so I ordered the large. The sleeves are pretty long, which I really like. Otherwise it fits slightly baggy, but I typically wear a women's large so I ordered the large hoping for a little bit oversized. The material is typical for what a normal sweatshirt is, but is a little more lightweight, which I like. It being a touch thinner allows for easier layering and not peeling it off halfway through the day. The graphic is nice, the colors are bold and crisp. I love Christmas and love having tons of different themed clothing to wear, so I'm super excited to add this to my stash.

Great
This Holiday sweatshirt is great, It's made great with soft materials. It fits perfectly not tight and not bulky. It's warm and can be worn over a t-shirt or a long sleeve shirt when it's cold outside. It doesn't twist or ride up. The design is well made and looks great. The colors are bright and look nice. It's great for the holidays but after they're over I'm going to keep wearing this because I like it. It's a great price because with proper care this sweatshirt will last for a long long time.

Quality Shirt!
Size: Medium, Color: Black Orange
A good quality shirt with an embroidered pattern. The fit was right on the arms and shoulders but ran big in the waist area. The fit really depends on your build. The price was fair for this quality, highly recommend!
