The size is 100, but it has a slim design. I've taken pictures with a measuring tape to show the approximate size, so please check the images carefully. The color is red with small white polka dots. It's not down, but has synthetic filling. It's been worn a few times. There doesn't appear to be any noticeable stains, but there is some wear on the zipper, so please check the images carefully. The hood is removable, and the boa lining can also be removed. I apologize, but due to the thickness of the fabric, I will compress it somewhat for shipping to fit the size. There are no smokers or pets. I'm trying to sell it as cheaply as possible, so I'm afraid I may not be able to negotiate on the price. m(__)m
