Zesica Cream coloured multi-tiered dress size large

Zesica cream coloured multi tiered maxi dress Purchased from Posh but find it is a little too big for me. (I didn’t know measurements when I bought it from a show.) It is really pretty and reminds me of a wedding cake. New with tags. Note: there is one small run on one of the sleeves which was there when I received it. Size Large PTP 20” Waist 16” unstretched Length 40”
