Amira Technical Organza Oversized Long Sleeve Shirt Dress Little Girl Wearing Shorts Images at Christina Aguirre blog. An objet dart we released 18 units of Muwa last year and they sold out in less than a minute. Its only taken us 4 years but weve finally managed to recreate the technical organza fabric. This time around, Muwa comes as the Amira dress: a floor sweeping shirt dress. She is the moment, and there is no one like her. To save 40% of fabric which would otherwise be wasted, we have chosen not to use placement print. This means that each dress will have a different print pattern. We do this in an effort to be more sustainable but we also think that it keeps the dress super fun!
