April 11-12 was Spring Fling at Penn! Which meant only one thing: Sigma pulled out all the stops for their annual pre-fling downtown party ROUGE. This year ROUGE was held at The Roxxy, a nightclub located in Philadelphia’s Northern Liberties. Friends and classmates of Sigma came to kick off fling weekend – and a good time was had by all. Thanks to our fantastic social chairs Ashley Chan and Laura Zhang (Upsilon Class) for organizing such a fun party!
