This duvet set is very pretty. It isn't super soft, but it is in a guest room so that is not a deal breaker for me.
I got the set in yellow. Overall the main color is grey, there are two shades of grey, one cooler and lighter and one warmer and a little darker so it should fit with both styles of decor. The blue that comes through in the online picture is much greyer in person. The yellow is bright and sunny, but not overpowering.   

Pros: Very classic and fun pattern.
Cons: Not as soft as it could be.
