I hated Rococo when I first saw the series, to be honest. But that was because the Wiki has this ugly furry carpet I thought was part of the series. Now...it's my dream furniture. But I also like the Alpine series.
Gonna have to say Alpine series. Still trying to find all the pieces. The Nookling store has yet to even sell the flooring. Been checking every day, or I just have extremely bad luck and timing.
I love the Modern Wood series. I was floored when I first walked into Cally's home. Too bad I can't find a picture of her interior decorating that hasn't been fish'd.
This is a tough one! I adore four equally: Sloppy, Exotic, Sleek, and Minimalist. Each has their own special place depending on the look I'm going for. Exotic goes really well with other no-themed items, like the sitar, chaise lounge, fireplace, simple sofa, tea table, etc. And the sleek is my bedroom set. Minimalist is the way to go for a kitchen or bathroom since it already looks like it's made of marble.
As for sloppy, well...it's most representing what my room actually looks like.
Absolutely love the Rococo series, especially when it's customized in Black Gothic. I was expecting the customization to be entirely black when I first heard of it, but the purple is so perfect. *_*
