The button front a-line mini skirt is the current "it" skirt. I've been seeing it in a variety of fabrics including denim, suede and corduroy. With it's high waist, it's good to pair with a crop top or tuck in a blouse with long bell sleeves. Rock that 70's vibe.
Here are a few options to shop:
Denim: ASOS New Look Button Front
Cordurory: BDG Button Front Corduroy Mini Skirt
