This thread made me think about the newer trend of nipple bras. If you don't know there are multiple manufacturers making bras with built in hard nipples. it gives the appearance of having hard nipples even though you have a bra on.
I thought it was the strangest thing when I first saw it. However what I find interesting is that this is a product that is marketed towards women. Not trans women, or cross dressing humans, just women. Sometimes I think that trans people get a bit too caught up in making sure that everything is real and natural, or as real as can be. So things like using hips pads can be looked down upon because they are not real.
Sometimes women use products to help them feel more confident. Sometimes men do that also. There is nothing wrong with those sorts of things if that is what you want.
So I suppose if you really want people to see a camel toe and for whatever reason you feel the need to use something to help the area appear more camel toe-ish, then go for it.
