It's no secret that Demi Moore's got great style - and some of her past looks are still on our moodboards today. Case in point: Moore's polka-dotted white midi dress from the Cannes Film Festival, which we found a budget-friendly version of just in time for spring. A white midi dress is the perfect spring and summertime staple, and can appear extra elevated with the help of patterns and prints, just like the star's Elie Saab pick. Similar to Moore's dress, the under-$40 piece we found features a short-sleeved silhouette covered in black polka dots.
