No because I can tell by looks rather they are men or women no matter what they have on. Boobs are a dead give away. Facial hair is a dead give away. It does not matter what they have on. Adam's apple is another giveaway too. I can also tell by shape of their body too. I have seen men dressed up as women and I have no idea if they are transgender or a cross dresser or a sissy.
With children it's very hard to tell when they have no hit puberty yet because they all look the same. The only difference is what clothes they are wearing for you to tell if they are boys and girls. But if one of them decides to wear boy outfits, they are going to look like a boy.
