Collaborations are all the rage these days and none have been more hotly anticipated than Derek Lam for eBay.  I had the pleasure of attending a little soiree to celebrate this match made in fashion heaven this past week.  Derek and eBay turned Crosby Street into a summer block party that parked delicious food trucks outside while the interior of the boutique was filled with flowers, frocks and AstroTurf. On hand to toast the collection and shop were Bridesmaid Rose Byrne, Rachel Bison, Zoe Kravitz, and China Chow. Get your own dress online before they’re gone! Happy Shopping!
