A size 6x boy's tee from the local Salvation Army. It was stuff-a-bag day, so this is one of MANY goodies I brought home that day :D
Some people hate the look, like Sydne at Think Thru Fashion. Daniel P. Dykes at Fashionising likes the look with reservations. Fashion Online Malaysia and College Candy both urge trend-lovers to wear their crop tops the "right" way (I will note that the College Candy article is definitely cheap in their examples). Brandish discusses the oddity of the trend for men. Elle.com features the look in the Australian Fashion Week Spring 2010-11 trend line-up (technically, everything down-under is a season BEHIND the northern hemisphere, so it corresponds to Spring 2010).
For the link-phobic, some pix from the above links in corresponding sequence.
I really adore the Sara Phillips leather crop top, but those blue-grey satin pants just KILL me! LOL!
