- A mini doll of Isabelle was released in January 2014 and was sold only in bookstores and third party merchant sites. The mini doll was never made available for sale directly through American Girl, except when it was briefly sold as part of a two-book set.
- Isabelle cost $120 instead of the typical $110 (that was current at the time of her launch); the extra cost was assumed to be because of her hair extensions.
- Unlike the Historical, Best Friend, and previous Girls of the Year dolls, Isabelle was the first character doll to have ear piercing as an optional add on at the time of purchase.
- The Sparkling Step Shoes resemble the meet shoes.
