I got this dress from my grandmother she bought it for me during one of her shopping excursions she's no longer with us so this dress is very important to me I have not worn it but once in my life and so take very good care of it it is Spandex and it is made of velvet and it is very soft and it's got a little turtleneck to it and it sleeveless and it's dark dark purple and it goes a little bit past your knee when you're walking
