If you go to a vintage store:
1. Know what you like. Do research on the Internet before so you know if you are more a 1920's or 1940's girl. Look for clothes in the store that resemble the ones you liked online.

If not, treat it like a thrift store and follow the tips for shopping vintage in a thrift store that I have added below.
2. Try it on and pay attention to the measurements. Vintage sizes run different then sizes today. Some stores will include measurements, so know yours before you go in. Otherwise, just try it on. Remember that you can hem up, let out, and take in anything you need to with a sewing machine at home.
3. check for imperfections or tears. If you find some yet still want to buy the item, ask the sales associate for a discount, normally they will give you one. Mend any small imperfections at home.
