There is so many online vintage store.. and they offer a variety of interesting clothing. but sometimes we collide with doubt because they can not see things directly. but it sometimes also hampered by the cost of shipping is quite expensive.
But there's the offline alternative which is the cheapest-possible-close-to-free vintage fashion you can get!
Flea markets and yard sales are excellent sources for old vintage clothing at low prices.
Make sure to get there early in the morning (preferably right before they open) and get your hands on the most popular vintage items. Once they're gone, they are gone. It's about getting there first. 
And you can also stop by your local thrift store. There you can find shirts, skirts, jewelry etc. for just a couple of bucks. Examples are Goodwill, charity shops.
If you buy vintage clothes offline you have the chance to inspect the garments closely and check if everything's ok. You can also try it on to be sure.
