Has anything like this happened to you?

I was shopping the other day and decided to look for a new bathing suit. I had one in my hand looking at it and a guy (around 50 years old) walks by and said "that's too little for you". And I'm even in good shape and it was not skimpy looking or anything! I find it really sad that a 50 year old man told a teenager girl that when he didn't even know her. It really got to me more than it should have and now I feel a little insecure. So has anything like this happened to you? I know this is random but oh well ha :) Thanks for the answers.
