Leighton Meester style
I find her personal style a bit rough but I like these last couple of looks:

Also fond of the mix of designers: Celine, Chloe Sevigny for Opening Cremony, Derek Lam, Miu Miu.
The romper (which I looooooove) is Kettle Black

and is on sale for $49.50 @ Shopbop (with sizes S-L still available!)
