6 of the best looks at the 'Bridgerton' premiere and 4 that missed the mark

Styled by Aimée Croysdill, Coughlan wore a custom Danielle Frankel dress to the premiere.

The off-the-shoulder, structured bodice looked similar to a tuxedo vest, flaring out into a peplum at Coughlan's hips. A long train billowed from the waist, contrasting with the column skirt that hugged the star's legs.

Elbow-length white gloves and white pumps completed her elegant ensemble.

Wearing Versace, Newton paired a red and black checked jacket with a white shirt and black pants. He accessorized the look with brooches from Chopard.

The ensemble was different from the suits many men wear to red carpets, but it didn't have the glamour one may expect for the event. Holly White styled Newton for the occasion.

Bailey arrived at the premiere in a layered Brioni look.

A sheer, white top served as the base of his outfit, and he added an unbuttoned white blouse and a white suit jacket on top of it.

White pants and black shoes tied the refreshing take on a red-carpet suit together.

There was a lot to like about Ashley's Prada gown, from its strapless neckline to the sparkly fabric covering it from head to toe.

But the dress had so little structure that it overwhelmed Ashley on the red carpet, particularly since she paired it with minimalist jewelry from Suzanne Kalan and Anita Ko.

Overall, the look seemed to be wearing Ashley rather than the other way around.

Styled by Felicity Kay, Dodd arrived at the premiere in a strapless gown.

The black corset bodice flared at Dodd's hips in a subtle peplum, while the form-fitting skirt was made of blue silk. Two ribbons flowed out behind Dodd as a modified train.

Safiyaa designed Andoh's black-and-white gown.

The sleeveless dress had a white bodice, a subtle cutout under the bust, and a black skirt.

White ribbons attached to the halter neckline for a feminine touch.

Jessie didn't wear a shirt under her loose-fitting Stella McCartney suit, which was light blue and had white, vertical stripes.

The suit was chic, but it was hard to pay attention to it because of Jessie's bright-green block heels. The shoes would work with an edgier look, but they didn't fit the sophisticated suit.

Jessie told InStyle on the red carpet that sustainability is important to her when it comes to fashion, so she plans to rewear the suit at future events. She also told the outlet her boyfriend selected the green shoes for this event.

Carter's strapless dress was the star of her ensemble, as it appeared to be sculpted to her body like armor. The back of the dress was open, connecting the two sides of the bodice with thin strips of fabric.

A full skirt contrasted with the modern bodice, giving the black dress an edge. Carter's slicked-back hair added to the modern feel of the outfit.

Sarah-Rose Harrison styled the look.

Gemmell's floor-length black dress had a high neckline, pointed shoulders, and quarter-length sleeves, which featured sparkly detailing.

The glitter was a welcome change as the rest of the black dress fell flat.

The actor's hot-pink dress nodded to the Regency Era while still feeling modern and fun.

The off-the-shoulder neckline was lined with floral embellishments, while the corset bodice had exposed boning.

Tiers of ruffles covered the full skirt, which flowed into a dramatic train.
