Holly Willoughby, her sister and her mam watched the Royal Wedding in their wedding dresses

Holly Willoughby had a Royal Wedding viewing party to coincide with her sister's 40th and her mother's 70th birthdays

She said she'd do it. And she did it! Holly Willoughby, her sister and her mother all had a lovely day of celebrations dressed in bridal white.

By the way, how is Mama Willoughby 70?!

One of Holly's hashtag's was 'why not' and why not indeed? How many of you have worn your wedding dress again after the bg day? Let us know in the comments!
