1stDibs.com is the holy grail of vintage and antique everything! I used to use the antique furniture section for school, they have high resolution pictures on white backgrounds and awesome unique items, perfect for photoshop! But besides that, I started browsing the vintage clothing and jewelry section recently and I was blown away, here's some of my favorites --

1. Versace Shorts

2. Patrick Kelly Dress

3. Paco Rabanne Dress

4. Belinda Bellville Dress

5. Jack McConell

6. Versace Corset

7. Lazzaro Necklace
