Zara top size medium

Zara NWT size medium. Beautiful top with lots of gorgeous detail. Not sure of fabric. Substantial almost like a soft sweatshirt material but has a feminine flair. Cream colored Organza like hem and also at cuff of sleeves. The only minor flaw is the right sleeve cuff looks a bit soiled.(photo #9)I would think it would come out when washed. I have never worn it. Adorned with beautiful crystals at neckline and all down the back. A showstopper. Last photo taken near sunlight. I would call this color a creamy beige with grey stripe
