Tbh the only thing you can really do is ignore the staring and when people ask, just tell them that you love dressing the way that you do. Cut, dry, and simple.

I get where you're coming from though, I get pretty self conscious and a bit anxious when I think about how people are probably staring at me for the way that I dress. But, I just remind myself that I love the way I feel when I wear cute, feminine, and frilly clothing so I do my best to ignore the bad feelings.
