Investigators say the women captured on surveillance cameras stole from a Sephora store on Cross Creek Road in Malibu back on Nov. 3.
Officials say they shoved $3,600 worth of cosmetics inside a black booster skirt, which is a garment with a loose elastic waistband that can be used to hide items.
The women then took off in a black 2011 Toyota Sienna minivan.
Anyone with information is urged to contact the sheriff's department by calling (818) 878-1808.
