At the moment, preppy and private school-inspired outfits are really fashionable, which is why you should try to create this stylish little skirt and sweater vest combo. You can achieve a more laid-back and cool-girl private school vibe by leaving the white button-up shirt untucked from the grey pleated skirt. Additionally, a black tie can be seen peeking out from below the grey v-neck sweater vest while you are wearing this outfit.
