I recently got this grey maxi skirt from Yours. Super soft, stretchy jersey with a side split to show a little leg. Not that you can tell as its billowing in a breeze! The top is a ribbed, open backed vest that I picked up in Primark recently, along with the hologram sandals.
Vest is the same as above. Leggings are from River Island but are pretty old now. Platform plimsolls are from Primark and the bag is EBay.
