Quoting MILF !!:" We're not throwing it...my best friend asked me to get together a guest list because she'd like to throw ... [snip!] ... is people we invited to my first shower and I'm just wondering if they'd be like "Seriously? another shower for another girl?""
Oh well if someone else is throwing it I say go ahead!
Personally I don't see anything wrong with it, I just wouldn't have because I would be afraid other people would think it was tacky. But if you're not the one throwing it I think it's fine.
