That is Dwell's "Trellis" duvet set in light blue and white. Unfortunately, they don't make it any more. I'm fortunate to own it in both light blue and black. Maybe you can find it on eBay?

Yup, what icelandicody said. Sadly, Dwell doesn't make it anymore, but if you can hunt one down, I HIGHLY recommend it. I bought it in yellow a few years ago and it's absolutely wonderful -- holds up well in the wash, doesn't fade, and looks great.

i love those wall decals. anyone know where to get those?

The decals are from Blik

@icelandicody and ndj99987 Thanks so much! Any ideas of where I could find something similar if I can't find it anywhere?

Those wall decals are hideous. Who would seriously put those on their bedroom wall? Maybe my 12 year old brother.

I've seen similar stuff at West Elm over the years. Or if you're on a budget, check smartbargains.com. They have a lot of designs in king (fewer in queen) but some of sort of similar geometric things going on.

Not the same, but similar....

Also, I saw lots of pretty bedding here (which also shows the Trellis bedding, which is no longer available, as the others have said.

Theres a really cute white and grey duvet cover from CB2. It's not exactly like this one, but it's nice and reasonably priced. http://www.cb2.com/family.aspx?c=422&f=6207
