I remember a story years ago of a friend who attended a bridal shower and one of the moms - the bride or groom's, I don't remember which - surprised the bride with a stripper at the bridal shower.
I personally would have been mortified if a stripper showed up at my shower, where my mom and grandmothers were present.
There's a difference between the shower and bachelorette party. The bridal shower is to "shower" the bride with gifts to furnish her new home with her husband. The bachelorette party, like a bachelor party, is for the bride-to-be to celebrate her last night as a single gal with her best buds.
While of course it's up to you to decide what you want at either of these parties, not everyone wants a stripper at their shower or bachelorette. Let the hosts of these parties know what you want. After all their both parties in your honor.
PS - I am a fan of edible favors for weddings and showers so talk to your chocolatier about options that fit the party's theme or a wedding theme in general.
