You’re probably out of school but that doesn’t mean you can’t enjoy wearing a cute preppy school girl outfit.
But if you’re worried about crossing the line between preppy-chic and costume-y, try looking up to these celebrities for some styling ideas:
1. Make it look more mature by adding lace touches
Reese Witherspoon exuded a preppy vibe with her white undershirt collar peeking out from her Tory Burch sweater.

But her trick to looking great in this school girl-inspired attire is opting for a lace sweater and keeping it loose over the skirt.
Throw in a pair of pumps to cement the look. Get this:

2. Going for pleated skirts? Try something in leather

Pleated skirts and collared shirts scream “school girl”. But to make it look more interesting, opt for pleated leather skirts instead. Get this:

3. Wear your a-line skirt with a pair of tall boots

Think ‘60s school girl outfits. A-line skirts are a staple of that era.
But rather than wearing a collared shirt, opt for high-neckline sweaters and then finish off the look with a pair of shin-high or knee-high boots for a nod to mod style. Get this:

4. Look for a box-pleated skirt with a slightly longer length
One that sits just above your knees would give a classier effect just like what Olivia Palermo was wearing in this outfit.
She wore a white, black and red colorblock dress by Valentino, a green leather fringe flap bag, and pastel pink Oberoy ankle strap sandals by Sergio Rossi.

A long-sleeved collared top and a pair of sandals would work quite nicely with your skirt. Get this:

5. Pick a tartan skirt with a modern silhouette

Tartan skirts will always have a preppy vibe to them. Try something with a flounce shape or a modern mini cut for a more grown-up feel to your look. Get this:
