First of all, go to Dorothy Perkins! She has the hook up for midi skirts.
Dorothy Perkins Midi Pleated Skirt, On sale for $39 (originally $55).
Petite Pink Midi Skirt, $35.
Next we head over to Asos, who also carries many different kinds of midi skirts:
Full Midi Skirt In Jaquard in Stone (nude color), $35.75. Silver (grey color), $49.86 (on sale from $71!).
If you want something a little more floaty, try Asos Full Midi Skirt, $41.39.
Maybe you'd like to try something with a bit of a punk edge? Wear this with a black tee or a white tank top with leather booties. Or you can channel its school-girl roots simply by switching the shoes to loafers and keeping the accessories feminine. Asos Midi Kilt Skirt, $33.87 (on sale from $84.66!).
If you'd rather do plaid without a pre-set look attached, try this Navy and Green Check Midi Skirt from Dorothy Perkins, $27 (on sale from $49!).
Finally, I have a midi skirt that has more of a body-conscious fit, but I love the print and even the top Asos paired with it.
Hope that helps, Elizabeth!
