I spent the evening shopping uber-chic French clothing brand Sézane's winter and holiday collections. Here are the vintage-inspired and retro-yet-ethereal trends I spotted from Sézane: 
1. Season-agnostic silk and jacquard pieces were the stand-outs of the collection
2. Plum red, navy and gold shades, colorful trousers
3. Jacquard trousers
4. Tulle Misty Copeland-esque caramel skirts 
5. LBD meets rainbow
6. Silky LBD pieces
7. Victorian necklines
8. Pussy-bow dresses
9. High-neckline dresses
