On places like Ebay and Etsy, you can find a TON of things that will look great with your outfits!
I think purses and accessories are the best, but you can often find some really great clothes.
Being more of a gothic or classic style, you will benifit the most.
The best part about vintage, is that you can often find it rather cheap! (like, a 12 dollar leather bag)
So here are a few things I thought were really Lolita-able vintage!
Note: these are all from Etsy, as I really don't use Ebay much. :/
Purses (I'm a bag person, lol)
www.etsy.com/view_listing.php -A rather sweet one
www.etsy.com/view_listing.php - say it with me: "country Loli!"
Dresses- a lot of vintage dresses are either not full enough, or too long; the latter is easy to fix.
www.etsy.com/view_listing.php - a little expensive, but cute.
www.etsy.com/view_listing.php - I like the mega-poof...
www.etsy.com/view_listing.php - some classic shoes!
www.etsy.com/view_listing.php - cute locket
www.etsy.com/view_listing.php - And I had to include a teacup!
I hope you liked somthing there, and if not.... then maybe you can find somthing on your own?
