Julia Roberts's Most Memorable Red Carpet Moments

Only America's sweetheart could still look adorably feminine in a gender-bending, oversize Giorgio Armani suit, which she reportedly bought off the rack.

Her menswear-inspired style continued with this lavender double-breasted outfit, which was a cross between a large tailored blazer and a minidress.

When she wasn't blurring fashion lines with shoulder pads and suits, she stuck to her other style signature: the little black dress. This one, by Dolce & Gabbana, was a sexy take for the young star.

There are few women who can pull off pink satin, and Roberts is one of them.

The star even added a touch of pale pink to her classic strapless Calvin Klein LBD.

By this point, Roberts had achieved true superstar status, and this bright red Vivienne Tam sheath was an understated look to wear to a major premiere. Still, it was a statement-making moment, not just because of the pop of color but because she revealed unshaven armpits — a look that made global news.

Her Oscar win in a dramatic velvet vintage Valentino column dress — from the designer's 1982 collection — wasn't just the most iconic red carpet moment for the actress herself, but it was perhaps one of the most memorable dresses of all time.

Roberts cocreated this figure-flattering champagne gown with her go-to designer Giorgio Armani. Fun fact: the center brooch wasn't a multimillion-dollar diamond accessory but a simple costume pin.

As a cohost of the "Superheroes: Fashion and Fantasy" Met Gala, the star gave a subtle nod to the theme in a sparkling, beaded silver gown from Armani Privé, with Giorgio serving as her escort.

Some believed it was an homage to her famed Valentino moment, and others thought the Dolce & Gabbana gown-shirt mashup was confusing, but regardless, the look had everyone talking.
