What nibbles to provide at a cosmetics party?

[TheSleepFairy]

I have agreed to host an open house cosmetics party but I am really unsure what sort of nibbles & drinks I need to buy.
If everyone who said yes turns up I am looking at around 15 people.
So drinks wise I though a few bottles of soft, some wine, soda & Jaques - maybe 2 of each? I'm hoping people will bring a bottle if they want a drink as I don't want to spend all my budget on food instead of make up!!!
