Ladies, hurry up and drop off those old prom dresses at Ella Rue. The boutique, owned by Krista Johnson, will accept donations for Once Upon a Prom, a non-profit, now in its fifth year, run by Ashley Taylor of Ann Hand LLC. The P Street shop held a fundraiser, March 31. The dresses are provided free, one per each young woman who otherwise could not afford it. The 2011 Prom Dress Giveaway at Eastern Market is set for April 17.
