I always like to stop in at Margaret OLeary on 23rd. And, I would add, stop in at Cargo (Pearl District) -- it is an AMAZING place. You might find clothing there if you like ethnically inspired items, but there is so much more to peruse: local jewelry, housewares, decor, antiques, and the store itself is just like nowhere you've ever been. So worth the trip, such a visual experience.
Thanks for that link to Frances May, Anna. Definitely going there!
