The 25-year-old actress, who plays the lead role in the new fashion-centred drama, told Digital Spy that her latest role is totally different to others she's done.
"Material Girl is set in the fashion industry and we follow Ali Redcliffe and her rise to fame within the industry," she said. "When we meet her, she's working under a huge big label but in episode one it all goes wrong and she has to start from scratch!
"Ali is quite complicated - she's a lovely character to play. She's quite dramatic and over-the-top too, and thinks with her heart, not her head. I hope everyone can relate to her because she touches on what most people go through."
Crichlow also confessed that her character is involved in a love triangle, a plot which she is thankful for.
"She's got three men in her life, so her hands are full. Someone's gotta do this job... poor me!"
Material Girl begins Thursday, January 14 at 8pm on BBC One.
