From your description, it doesn't sound like any sort of official would call it for being inappropriate.
The bigger question is how you feel in it. If you feel fine, rock it. If not, you could easily switch that out for a thicker mesh or a coloured mesh. Body suit could work but may just draw more attention if it doesn't match up perfectly. If you sew at all, it'd be easy to swap out, or you could find someone local to do it for you.
But like I said, if you feel comfortable in it and think it looks good, then don't worry about it.
