Triathletes, I need your help on something please and I'd feel dumb asking elsewhere!!!!

I am doing my first superspint on Saturday~~ 1/4 swim, 17 mile bike, 1 mile run. I swam when I was a kid, but nothing major and nothing related to distance. I just started "doing it the right way" about 3 weeks ago to get ready for this event.

My question is, am I going to look like a dork wearing a wet suit for only a 1/4 mile swim? I don't think so, but wanted to check with you fine ladies!! I can do the swim no problem WITH the wet suit, but can't without it. I'm afraid that if I don't wear it, I'll sink, so I guess I'd rather look like a dork than sink! Am I a dork or just thinking too much?

If you are wondering about the water temp, I'm in Wisconsin, so it'll be pretty cold.

Thank you all!!!!
