Peaches is a Posh Totty, along with Chloe and Chelsea. She is rather like Chloe, hanging on to Chelsea's every word and believing whatever Chelsea says.

Peaches is shown to be rather dumb, although she and her fellow Posh Totty's enter School Challenge. They only win through cheating and seduction.

When former Head Girl JJ French comes back to St Trinian's to teach the Totty's how to act like braniacs (for School Challenge) Peaches remarks:

JJ: Now here's a little tip that I learnt from Paris.Edit

Peaches: (excitedly) Hilton?Edit

JJ: (raises eyebrows) France.Edit

Peaches is portrayed by Amara Karan.
