I love eBay for Vintage shopping !

Its so cheap and easy but like everything else it comes with a price.

I found these three tips really helpful:

1. Check out the sellers’ feedback! There are amazing sellers on eBay, but there are tons scammers too. Stay away from sellers with negative feedback (even if their cloth look the coolest ever).
2. Make sure to measure! Finding the right size can be tricky. A vintage 14 is a modern 8 at best, so never go by vintage sizing. Drag out your measuring tape and measure the bust, waist and hips of your favourite dress. If there are no measurements listed on eBay, or you need additional measurements, email the seller to get the info.
3. Make note of the date and time the auction ends! It sounds silly, but a lot of people end up missing something they really wanted because they forgot the end time (those people are me)

One last tip - checkout MakiMaki-Vintage, just found them on eBay, so fab (stole the pics from them).
