This is a ZARA velvet dress. It's made of very sturdy fabric that shimmers depending on the angle. It's not flimsy, so I don't think you'll need to worry about getting cold from air conditioning. I've only worn it once to try it on. Would this be suitable for weddings, parties, hostess dresses, or birthday parties? When shipping, I will compress the dress and ship it anonymously. As stated in my profile, I generally do not respond to price negotiation requests or discounts. I may block users who make excessively large price reduction requests, as I may consider them to be malicious. Please check my profile for details on pricing and shipping. Thank you.
