Top plus size model Crystal Renn walked for designer Zac Possen on Saturday September 11, 2010 at Mercedes Benz Fashion Week. Sporting a yellow jumpsuit Renn, ripped the catwalk in her first appearance at this year’s fashion week. We have seen reports of here size being a 6, 8, 10, 12 and 14 all for this show! Does it really matter? The fact is that she is beautiful and works the products. That’s the whole point, size shouldn’t matter.
