If you said Stella McCartney you'd be correct!
The British designer created a "simple and understated, off-white dress to the knee" for Nancy Shevell who tied the knot with Paul McCartney at Marylebone Town Hall in London this weekend.
Stella also designed her papa a bespoke navy blue suit and dressed all the little ones in Stella McCartney Kids.
