ok I'm trying to come up with a list and I see alot of threads like this here so I guess I'll try this, I'm looking to come up with a list of B-Movie (preferably horror or comedy) who played leads in B movies but didn't go nude only to then go nude as bit part in a tv series/mainstream movie or preferably softcore. The idea of this is that the tv series softcore or movies are technically step-ups for them even though they're not the lead. Here's some examples.

in Bold are their names and the B movie they appeared non-nude in, in Italics is the part they were nude in.

Jordan Madeley - she starred as the hot friend in American Pie: Naked mile and was in the B horror 5ive girls, she avoided nudity in both but recently starred in an episode of Femme Fatales showing T&A.

Augie Duke - I noticed her as the bitchy lead in a B horror/thriller Lure: Fight club for girls(or something like that), whilst there was nudity it wasn't from her despite good chances to be nude. She recently showed full frontalness (is that a word?) in an episode of Chemistry.

Hayley Marie Norman - was a deal or no deal girl then appeared in B horror movie Rest Stop or it's sequel not sure, she didn't really show nudity in it but showed side boob. She then went on to have a bit part in the TV series Crash and showed off her great tits.

Jenny Mollen - Was in some national lampoon B-movie Cattle Call which gave plenty of chances for her to be nude but only showed side boob. She then showed great T&A in the TV series Crash.

I'm sure there are more and I'll try and find some, just a couple of things that I'd say wont qualify:

If they appeared nude in the B movie then it doesn't count.
If they appeared in a Tv series then went nude in a B-movie it doesn't count although that could be a good thread, (ie. Roxanne Pallett in Lake Placid 3).
They have to have appeared nude in softcore or as a bit part in a tv series or movie.
If they're a mainstream actress it doesn't count, I believe there's a thread for that already.
Really it should be from going from a lead in a low budget movie to bit part in a mainstream tv show or movie, but a lead in softcore would be fine.

If you know any please post, thanks.
