Hello, I am requesting help in determining what size to order for velvet slippers. The shop which sells them is in England and I am, sadly, not in England; in fact, I am on another continent and that means I am unable to try on any for proper sizing. For those of you who own velvet slippers, do you find that you have to order down a size or two, or do you just order your usual shoe size? Looking forward to your knowledge and help! Thanks!
