pamper evening shoot :os

[cari-strong]

Ok, i'm new and after any advice I can get. A friend has asked me to assist on a fundraiser event at a local school, taking photos of the mums at a pamper eve. I do kids photography as a main stay, but they always tend to be action shots or silly poses.... I don't think I know where to start with doing serious, possibly sultry, looking photos.
So far in my head I have camera on tripod to add the flow of mums thru the shoot, black background and 'mum' sitting on stool but as for lens, or lighting have drawn a blank

Anyone with any advice, sample shots of what I should aim for would be most appreciated!!! Please :-)
