Wearing a vintage piece can be very tricky, trust me as much as you want to look retro, you don’t want to look old.
I have some few tricks up my sleeve when wearing vintage and I'll state some of them below:
1) Make sure it’s an item that has its own uniqueness, makes it stand out
2) Try giving the outfit a modern twist, a statement jewelry (my trinket did it for me), a bold glasses or something that gives it a modern flare
3) Always try to put in your own style, like I did with the hat and the Shoe
