I just discovered this little boutique across the street from the Tractor in Ballard. It has both new and vintage clothing, but the twist is that many of the vintage items have been screenprinted with cute little graphics (a sketch of a bicycle seems to be popular). Sometimes the results are very cool.
The new stuff includes designs from No Star clothing. I hadn't heard of them before, but I liked some of their designs a lot.
They also have cool little touches like handmade wallets and hand-embroidered ties.
