Continuity mistake: In episode 8-20: All Things Being Equal, while Lily is going to a feminist protest with Claire, Gloria, Haley, and Alex, Alex said something like 'The women burnt their bras', and Lily says 'Not me, I just got my first bra'. But in this episode Lily steals a bra because she's embarrassed to ask Mitchell and Cam to buy one for her.
Answer: Mitch is upset that his dad doesn't seem to support his getting married. When they talk about Jay's friends not coming to the wedding, Jay makes it seem like Mitch wouldn't want them to come anyways. Mitch sees it as it's actually that Jay doesn't want to invite his friends to his gay son's wedding because he's embarrassed and uncomfortable about having a gay son. Essentially Mitch sees it as if he was marrying a woman, Jay would be willing so spend money on the wedding, host it at the club, and invite all his friends to it.
