Put on a shirt and some pants and it wouldn't be as bad. It will probably be cold anyway.

I think most 15 year olds wear less on the beach then that, but I'd say it depends on where you are going. If it's too school or a school sanctioned party, too much, to the church Halloween jamboree, too much, but to a house party with other 15 year olds, probably fine. Just kind of think, if you're questioning it now and having doubts about wearing it, there is probably a reason for that.
