I've only dressed up a couple of times for Halloween, but this was BY FAR the best Halloween costume I've had (homemade and store-bought alike). It fits great, and both the "dress" and cape fabric is quality material for the price. "Dress" is in quotations because the dress and cape are actually one piece. I didn't use the belt which uses velcro, but only because I had a better one that matches the costume.I'd definitely accessorize. This costume is great, but jewelry, stockings, and shoes really make the costume. My only complaint is a minor one. There are elastic rings that are attached to the sleeves that you're supposed to slip over your middle fingers. I did this, but from time to time I had to adjust it so that my blood could circulate more freely.To give you an idea of the fit, I am about 5'6", 135 lb, size 4-6, 34B. I had a little bit of room around the waist, and the length was perfect with heels. This costume would fit women with smaller and (definitely) larger busts than mine, haha.
