Another item I purchased* on my Boston trip was a pair of paper bag waisted harem-ish pants from H&M. They are basically the awesomeness.
10,000 BPM (Urban Outfitters) mens t-shirt. H&M pants. Converse sneakers.
This is completely dressing them down, but I probably could dress them up as well....
*Well technically Eunice and I share them, as we split the $50 price tag.
