Irregular Choice has collaborated with multiple brands and designers. A small collection of shoes created for Heatherette's 2007 collection reportedly led to demand from the likes of Mena Suvari, Theodora Richards and Lydia Hearst; and was followed up by a spin-off range called Heatherette Loves Irregular Choice in response to fan demand. For two years they produced a line in collaboration with the cult fashion doll Blythe, featuring the doll's image.
