I purchased this item here, tried it on, and wore it a few times. It's in beautiful condition with no signs of wear. My daughter, who usually wears a size 110, found it to be a perfect fit. I think it would fit comfortably if you usually wear a size 100. Please consider purchasing it. This is a cute character fleece onesie with a hood, perfect for keeping warm. - Color: Brown - Design: Character (hood with ears) - Material: Fleece - Style: Long length - Features: Hooded, cute character face Thank you for looking.
