Its not really trashy, I think that people tend to link leopard print stuff in general with sexy, no idea why. Some girls might be jealous and call it trashy but other than that no. As long as you don't wear it with like stripper heels haha. I see no reason why a bikini that is a solid color or has little flowers on it is any more skanky than one that's leopard print. So I would go ahead and get one, I think it looks cute :). As for the color I'm posting a link that has skin tones and colors of bikinis that are best for the said skin tone, and on there I guessed you were maybe a bronze to light brown, and it said earth tones which is basically the colors of leopard print :) so its like perfect, and if you want your skin to look darker maybe try one with a white base.
Hope I Helped :) and have a fun summer in your new bikini.
