Ginnifer Goodwin's White House Correspondents Dinner dress cost just $299.
The 'Once Upon a Time' actress donned the light gray gown from high street retailer H&M's new Exclusive Glamour Conscious Collection to the glitzy event in Washington on Saturday (28.04.12) and says she chose the budget garment because it was eco-friendly.
She told People magazine: ''I wanted something that was very earth-friendly. That was critical.''
Despite its low price-tag, the dress will still be difficult for shoppers to buy as just 1,000 of the limited-edition pieces were made. Each one is individually numbered.
The dress features organic cotton and silk boucle at the top, with an organza ruffled skirt and concealed zip at the back.
Ginnifer - who was a guest of NPR at the event - chose to add her own twist to the dress by teaming it with a simple black belt.
The H&M Exclusive Glamour Conscious Collection has been a hit with other celebrities on the red carpet, with Michelle Williams, Viola Davis, Kristin Davis and Amanda Seyfried previously spotted in dresses from the range.
