It is valuable, I feel, that people are aware of what attire is what. Recently I have been working in an environment where the raiment you have posted here (and in another place) would be considered
normal - in that it is the sort of thing that the majority would be wearing.
I will stick to the wording of that short (linked) definition: garments of this type..
..are not "the same as would be expected" - dressing like this would be "unusual" (but nobody would mind). Whether one were a prostitute or not, clothing tends towards the outré, fancy dress is popular and the "ordinary" mode of dress is flamboyant in the extreme. That is the norm.
Of course it is entirely possible to wear fancy dress (
e.g. a gorilla suit) and still be modest. In this environment ones availability as a prostitute is indicated by other means.
Thank you for raising the issue, Lycia - it will be of much value to some of the teenagers seeking the path to tread. Satan extends temptation in the direction of all young women, and I admire your courage in exposing yourself to his jibes in this way.
