Manhattan —

Brides-to-be, soggy after waiting in the rain for hours, ran into Loehmann’s seeking discounted designer gowns as part of the Chelsea store’s  “Grab the Gown” promotion.

Gown seekers and their families dashed up two flights of stairs into what seemed to be never-ending aisles of white, filled with 800 gowns, including designs from Christian Wu and Demetrios, among others. Gowns that retail for up to $11,000 went for $1,000 or less. The event teamed Loehmann’s and cable network WEtv, which features several bridal-related shows.
