Akira tulip maxi dress

I'm not sure if this model is 7' tall or what but this dress is almost floor lenght in the back on me ( maybe cause it's a size L). Excellent, barely worn condition. Silky fabric, flowy and adorable. Has pockets! Elastic waist with detachable tie belt. Elastic waist laying flat: ~13" ( will stretch to ~22) Armpit to armpit flat:~17" Lenght in back from waist to hem: 40" The pattern and fabric is sooo adorable! Steel grey/silverish with white, blush flowers and black leaves
