I recently had a request for a couple of romper designs featuring a zip in the back. The zip in the back is to stop little ones from being able to pull off their clothes. One design is a full legged romper suit with an asymmetric zip reaching down one side. The other is a short leg with or without sleeves and a zip that reaches the middle back.
Both designs are currently being tested and should be ready for release soon. They will be available in sizes 0-14 años.
