If you're looking for shabby chic, rustic furniture and decor - look no further! I LOVE Rust & Roses and my house shows it. It can be hit or miss and pretty overwhelming, so I prefer going with a purpose, but usually don't leave empty handed. They have a huge variety of furniture and different washes and the price is right. I usually can't get over how reasonable the prices are. We've purchased a mantel, couple dressers, chair, table, etc. from here and have always been thrilled with our new treasures.
I agree - the owner isn't over the top friendly, but I prefer her non-agressive approach and lets you just walk and browse. Be sure to go out back and scout for outdoor finds - windows, doors, patio furniture, etc.
If you have more money to spend also check out Figs, Paris Envy and Melrose Vintage. All similar stuff, but Rust and Roses prices are the best.
