If you live in the US, you’re very lucky, because you can shop at Ruche without having to worry about the import-taxes etc. you pay when you have the stuff shipped to Europe.
Ruche sells very affordable, pretty unique pieces and LOTS of them are Blair-ish. Here are my favorites available online right now:
There’s an afternoon tea I need to attend
I have an appointment with my professor
Meeting of the drama-class
I’m meeting Serena at the museum (well, the stairs leading to it)
Meeting Chuck in the park
