The O.C. Bargainista:

This is a big weekend for local bargainistas (and bargainistos). One of the hottest trends in discount fashion is the pop-up store, which appears for a very limited time and is passed on via word-of-mouth. Graffiti Beach, one of the leaders in pop-up shopping, is opening one from 1 p.m. to 8 p.m. Saturday and noon to 5 p.m. Sunday at the Camp, 2937 Bristol St., Costa Mesa.

The two-day-only sale will feature wholesale and below (yes, you read that right) pricing on men’s and women’s fashions from brands like Jedidiah, Nimo, Vim Trousseau, Angel Eyewear, Freedom Artists and KDikio Vintage — along with many more.

There also will be an art sale, bikini fashion show, free food and live bands. Also upcoming: their Urban Arts Festival at UC Irvine on March 10 and 11. For more information visit, www.graffitibeach.org.
