Wilds, as a species of soutien-gorge, is a catch-all that includes any tops (or excuses therefor) which do not fall into any obvious species, in a sense wilds are beyond classification. So in this respect it may be best to define what a while top is not.
Wild Top Nots
Wild tops tend to be rare, and the student of Bikini Science is advised that what may be thought to be examples of wilds at first sight are often classified as species in their own right. The species may be obscure, but still well-defined.
Thus wild tops are not halfbras, cutouts and demi-bras, pasties, breast drapes or towels laid over the breasts, spider bras, nipple rings or other adornment, hands covering the breasts or nipple, or even the absence of top. Consider, for example, the difficulty of classifying this "costume," which consists of a leaf held in front of the breasts (EC0732F). It's not really a topless, and it's not hands either.
Debate has also suggested than when a particular species assumes the extreme of ridiculous that it "becomes wild." These advocates would argue that tops such the pico halter (JD89I0), the narrowed tube bandeau, or the see-through metal halter have all "gone wild," not unlike a plant or animal that has dispatched from civilization. This argument, which also applied to bottoms as well, denies the "excess of species," to quote a reader, who adds, "and excess is the foundation of the bikini!"
Soutien-gorge that have failed to find a home elsewhere include flaps that hang over the breast (PB87UC), the Orange drink cartons "worn" at Watkins Glen (WG7361), and a few other hard-to-classify Thrust band outfits. Ornamentation with encircles the nipple, but fails to cover it, definitely falls into the category of wilds (EC6510, JD89FD).
There has been debate in the community whether painted liquid latex tops belong in the wild category or in the species in which they are painted, and absence a resolution of the experts they are left here to smoulder, at least for the time being.
Debate has also immobilized the classification of body paint and other decoration. Some argue that the painted breast is simply a topless, but when it comes down to splitting hairs, painted breasts are permitted in the Mermaid Parade in New York (MP9524, MP95A6, MP9609, MP9611, MP9664) where as unpainted ones are not, proving, if nothing else, that somebody perceives them as different. So for now, painted breasts are cast into this land of erotic uncertainty. Painted nipples may also qualify as wilds, but again, legalistically, these also qualify as pasties (T94050), and so since they can be put there, they are.
