Who hasn’t reflected on images and wondered, “What was I thinking?” Celebrities, like the rest of us, have been guilty of fashion faux pas. To say the least, these fashion choices are dubious, and we could just forget about them, but we can’t. We’re sure these celebrities share our sentiments.

While celebrities are known for their fashion sense, these ensembles have become memorable for all the wrong reasons. Some of these fashion blunders will astound you. While Cameron Diaz is known for her laid-back California appearances and minimalistic style, we think this one is a little too casual for us. Granny-chic is all the rage these days, but we think this pink off-the-shoulder slouchy sweater is a little too sweet for us.

In the early 2000s, Paris Hilton was a significant trendsetter. Many Y2K mainstays, including low-rise jeans, graphic tees, velour tracksuits, and denim micro skirts, are thanks to her, yet this outfit is diametrically opposed to her regular style. To be honest, in this tweed suit combination, she looks more like her mother Kathy. Isn’t her appearance showing her age? She’s almost fully hidden, which is quite un-Parisian.

That’s not a good look. At the 2001 American Music Awards, Britney Spears had a significant red carpet moment with Justin Timberlake, who was dressed in full denim. We’re still talking about it after more than two decades. While that style was memorable, this denim look is underwhelming.
