Light Weight but Not Hot
Color: Dark Grey, Size: King
Ok... I absolutely love this comforter. In fact, I use it on three different beds. The colors are perfect. The material is soft. It's extremely light weight, but it keeps you warm in the winter and does not overheat you in the summer. I have this in King and Queen, and the sizing has been good for both. I have thrown it in my washing machine multiple times, and it holds up well. Great quality, low price.

Navy is pretty, but doesn’t feel like a great quality set.
Color: Navy Blue, Size: King
I purchased the Navy. The color is great and the pleated pattern is a nice touch. My daughter has the white and it’s very soft. The navy is not, though. So that was disappointing. It’s also not breathable. It’s not thick, but just not breathable. I actually get pretty warm at night with this one when I don’t normally with any other blankets. It also seems on the small side. We have a king and always buy king, this just feels a little smaller. Doesn’t feel high quality. I would not buy again.

Very Elegant!!
Color: Bright White, Size: Full/Queen
Beautiful comforter set! its super fluffy light weight while still cozy, gives a clean expensive look. It arrives wrinkled up from being packaged, i never steamed mine but you could do that if you want a crisp look. I love the quality and looks more expensive then it was, highly recommend!

Excellent buy!
Color: Blush, Size: Twin/Twin XL
I LOVE this set! It is perfect all year long! I fold it down in the summer to just cover my feet. In the Fall it’s perfect weight alone and in the colder months I use a blanket underneath! Everyone says it’s Beautiful! The color stays true wash after wash! It retains its shape well also! The pillow case is exactly like the cover! It also retains color & shape! It’s soft and you can just curl up in it! The quality is just as good as some other very expensive brands! This is great value for the money!
