I haven't tried this but Demeter has a peach fragrance:
They also make Fuzzy Navel (Peach Schnapps, Vodka and Orange Juice): http://www.demeterfragrance.com/5808...zzy-Navel.html
B&BW used to sell Sparkling Peach-- maybe you can find it on eBay?
One peach that many seem to like is Keiko Mecheri Peau de Peche (http://www.luckyscent.com/shop/detail.asp?itemid=16412) but I think it is not just a simple peach. Haven't smelled it.
Mitsouko has a peach note but is certainly not a simple peach.
