Two piece set from Australian brand, Grace Loves Lace. It's the Belle Lace Top ( and the Silk Split Skirt ( in the Oyster color.
This set is BRAND NEW! Never been worn. Still in the box from Australia :) the size is XS for both pieces which is about 0-2 sizing. 100% silk skirt is absolutely stunning on, and the top is French lace.
Would prefer to sell together.
