Need help remembering which movie this is

[shawn703]

It was a comedy from the 80s I believe. In it a couple is going to get married, but the bride-to-be had posed some years ago for a magazine like Playboy, but her future husband didn't know. When she went to meet his family before the wedding, I think it was his brother that asked her if he had ever met her before. It wasn't until a comedic event at the pool that the brother suddenly remembered where he saw her. Anyone remember this film?

1. do you remember any stars or character actors from it?

2. Unfortunately no...

I'd just imdb it and figure it out. . For some reason I can picture Andrew McCarthy as the brother, but it's been so long since I've seen it I could be way off.
