So beautiful I love it! I got the biggest size and I’m a size uk 10 I got it so it will shut my sister also loves it and she’s a size uk 16 and it fits her perfectly so I’d say 3XL is a size 16 any size up might be a bit tight. it’s so pretty and I’m so happy with it. Can’t believe how fast it came. It has no weird smell at all which is amazing and it’s super fluffy. Girls get it it it’s everything !!
