Zara Patterned Longsleeve Maxidress

Zara patterned floral button down maxi dress. Longsleeve dress has pockets abs belt loops to add your own belt. There is a missing button lower down, honestly didn’t even know it was missing until I went to list this! Never worn. Size XS. Technically is it new without tags but haven’t listed it as so given the missing button. Sort of a midi maxi length
