The Daring Dresses At The 2021 Cannes Film Festival

4. Abigail Breslin
How gorgeous does Abigail Breslin look in this floral Oscar de la Renta dress? She wore it to a photo call for her new movie, Stillwater. The actress, who we've watched grow up in movies over the years, is now 25 and her career is still thriving — as is her fashion sense. 

The star mentioned in an interview that it's "stressful" to walk in heels at a big event, however. "There's definitely a lot of stress when I go to a big red carpet - what if people hate what I'm wearing or hate what I look like or my hair is not in the right place? But you have to remember that there are more important things going on in the world and the attention span is so short," she told WWD. "In the end, you have to just go with what you feel in the moment. I learned that there's no way I can survive in this industry without getting a thick skin and not paying attention to all of that."
