As a mother and grandmother, I agree with all the above. If the girl is 10-14 or so age group then any costume should be IMO a choli style top with some fringing, older girls could choose a modest bra style top. I do like the idea of the dedicated child/youth dancer using a prop, it would take that put out there sexy look.
We hear the world over of some young girl, often prebuescent
who has been abducted etc, and gasp in horror, but personally when I see these kids wandering around in street clothes half naked, I do have to think to myself that often the inappropriate dress draws out the sickos more often that some years ago. I know that the sickos would still trawl the streets etc even if you were dressed in a sack from chin to toe, but can't some mothers AND childrens designers see that they set the kids up for attack physically and verbally. Yes everyone loves to be fashionable but there is fashion and there is 'ick' and sadly there is more 'ick' in the kids fashion industry than fashion these days!
Woops a bit off topic there. getting back to dance. maybe if young girls are learning then any comps or dance get togethers should be only for families of the girls and not open to public so the girl can show her "expertise" and the family can celebrate with her ... of course keeping the girls costume at an "appropriate" level. Ok off my soapbox
