Ever heard the expression, ‘cramming 10lb of spuds into a 5lb bag?’ Well Mariah Carey brought a whole new meaning to that expression as she attended Tuesday night’s Neighborhood Inaugural Ball for the incoming president, Barack Obama, wearing what could have been the prom dress she wore when she was 18 years old and weighed 18lbs less.

The full length black velvet trimmed, lace dress by Dolce & Gabbana was holding out as best it could while the Hero singer belted out her tribute to the occasion.

Does this dress come in size 18?
