Vector formats

I plan on having a picture printed on a shirt. I do know the shop needs it in vector format, but of course I forgot to ask about the exact file format.
So, can anybody tell me some common formats, which are likely to work?

So, that's your answer? You're saying anyone can read .svg?

They probably want an EPS file.

But since SVG is an open format, they'll be able to convert that to whatever they want anyway (unless they're morons).

P.S. they are ``professionals,'' thus idiots.
