Hasan has collaborated with superstar Cheryl several times. Firstly Hasan was asked to design a stage outfit for a performance of the single "Under The Sun" in 2012. The statement look featured silk jogger trousers emblazed with pop art icons, paired with a colourful leopard cropped blouse. Later that year Hasan designed a etherial purple silk gown with a chiffon train for the "Million Lights" tour. You can see the creation during Cheryl's performance of "3 Words" and "Parachute" as well as being featured as the cover of the DVD. Lastly for the reunion of Girls Aloud, Hasan designed 5 identical hot pink, silk jersey dresses which made for a striking cover for the comeback single "Something New."
