Wanna buy a bag? If so, do it tomorrow, when L.A.-based designers Sheila Nazarian and Laura Darrah unveil their spring 2010 collection of Treesje handbags during a trunk show at Saks. The ladies will be on hand to answer your purse-related queries and the first ten people to make a purchase get a free bracelet from Treesje’s fall 2010 collection. If you’re not one of the first to buy, no worries—anyone who buys anything throughout the event gets a free cosmetic pouch.

Saturday, March 27. 4 p.m. to 6 p.m. Saks Fifth Avenue, 9600 Wilshire Blvd., Beverly Hills. 310-275-4211
