We see Serena in the episode Raiders of the Lost Art, sporting a fun and bright scarf. I really love how it starts really pops against the rest of her dark outfit.
Serena wears these Repetto ZiZi Oxford Flats ($285).
Here is her Jimmy Choo Lara Woven Shoulder Bag ($2150).
She is also holding the Marc by Marc Jacobs Dreamy Logo Laptop Case ($68).
This is her Theodora & Callum Orange Multi Diamonds Scarf.
