You're Invited to Mary-Kate & Ashley's Coolest Parties

Costume Party (1x8)

: 01, 1998

In You're Invited to Mary-Kate & Ashley's Costume Party, Mary-Kate and Ashley look back at fashion over time in the 1950s, 1960s, 1970s, and 1980s before deciding on having a "come as you are" party (where you go to the party dressing in whatever you're wearing when you get the invite) with their friends.
