I'm from the US, so the concept of the chav doesn't really apply, but I like these ones:
Abby (preferably as a nickname, but I think it's workable on its own)
Becky or
Becca (again, preferably as a nickname, but I think they're workable, especially
Becca)
Imogen (well, I like Imogen
e a great deal; sometimes I think I'm the only one on the planet [or at least BtN] who doesn't like
Imogen at all :P)
Jazmine (spelled
Jasmine, I like it a good deal)
PortiaRikki (as a nickname, I think it's perfectly nice)
Shannon (for either sex--I think it's one of the few names that really sounds nice unisex)
