the four-letter appellations for females of relatively easy virtue ...

Such as minx? Or vamp? These are probably more appropriate if the attention-seeking is simply the means to a more devious end. Coquette is, unsurprisingly, most likely to be closest to a direct translation. I imagine there would be some term based in mythology if the attention is the end unto itself - Siren, Nymph - Nabakov's nymphette?
