I had a friend who received a wet bathing suit bag as one of her favors for being a bridesmaid. This is a great/useful idea, but I don't know a good place to order them. I googled wet bathing suit bags, but I see some with draw strings. I like ones that have a zipper to close it. I saw this girl's wet bathing suit bag, but I don't think it would be big enough for women's bathing suits. Just for an idea of what I am looking for I will paste the link.

Does anyone have any leads on where I can find something like this for women, so I can use this for my bridesmaid's gifts?
                 
                
Re: Bridesmaid's favors
I use grocery bags.
But I give you points for creativity.

If you like the option you posted, buy that one. You may want to ask your bridesmaids if they prefer blue over pink, however. I have a strong dislike for pink, and would much rather have the teal / blue colored one listed as an option below.
