Really all you need is some vintage finds and a little bit of classiness. For her makeup stick with a frosty pink and done eyes with a small cat eye and perfectly done eyeshadow. Don’t forget the bronzer, Jackie O had a nice tan glow at all times. Make sure you have some sort of pin to keep the hat on, and faux bob your hair for full effect. Voila!
I found the suit at a vintage store. You want to look for one with a 60’s vibe: a swing jacket, or a pastel color. For the hat make sure it matches your outfit and can hold its shape. Then you need HUGE sunglasses and pearl accents. Don’t go to high with the heels or you’ll look like a sexy secretary or something ridiculous.
