Guys I think she means if she would look weird in a swimsuit while other girls are in bikinis I don't think it would look weird at all, unless the swimsuit looks really dorky
no because when you swimming in this time you must use swimsuit.
Let me correct your question first. It should be, "I'm fourteen; would it look odd to wear a swimsuit at the beach?". Or something along the lines of that because your question has bad grammar and doesn't make sense. Anyway, no it wouldn't be odd to wear a swimsuit at the beach. If you feel uncomfortable wearing one, then wear a pullover dress over it until you get into the water.
