the rococo set in pink and white
the regal set in pink maybe
the alpine stuff with light wood color and a design or clothing pattern could also work
the sloppy set is light colored for the most part
Minimalist series can be customized to pastel green, gray, and brown.
I love pastels! I generally collect just a lot of light/white/colorful stuff... balloon furniture maybe? Kiddie furniture is more bold than pastel, but I love them as well. They look very good with a sky wallpaper and cloud floor!
