The 9 best looks from the ‘Downton Abbey’ season finale

Talk about going out in style.

While the overall quality of Sunday night’s “Downton Abbey” Season 4 finale is still in question (The Daily Beast called it “the depressing demise of a once-great show”), fashion fans and critics alike can agree the costumes killed it in the best way possible.

The episode proved especially pleasant for lovers of pretty things. Pastels, feathers and tiaras galore came courtesy of Caroline McCall, the series’ lead costume designer, who won the honor for Outstanding Period/Fantasy on Saturday at the 16th annual Costume Designers Guild Awards.

Alert: no spoilers here. Just our favorite looks from the 90-minute episode’s seemingly endless cycle of outfit changes.

Lighten up, it’s the ’20s!

The young ladies of “Downton” kissed corsets goodbye a long time ago, but in the season finale, it was nice to see those loose, boyish flapper silhouettes offset by feminine colors like dusty rose and power blue.

“Hatter” up

From Lady Edith and Martha Levinson’s colorful, posh toppers to their staff members’ muted styles, headgear got a lot of airtime.

Crowing achievements

Who is Freda and what is her relationship with the prince? It’s hard to tell. Really, we’re more focused on the tiara, which any bridezilla would die for.

Retro-casual

Who needs beads and finger waves? Madeleine is stunning in this simple white blouse and ivory sun hat.

“Downton” does… Derek Lam?

Color drama

We love a good visual foil. House darling Rose got to wear a pretty pink dress. Meanwhile, poor Lady Edith got shafted (yet again) with this glamorous shade of khaki.

Life’s a ball

Rose’s ravishing red ball gown added some much-needed volume to her narrow waist repertoire.

Or is it a beach?

Because Daisy looked damn good in her pink day dress.

A courtly coming out

Rose couldn’t have picked a prettier dress “coming out” for her moment with the King George, Queen Mary and Prince of Wales at Buckingham Palace. And her and Cora’s feathered headpieces could have been straight out of “Cinderella.”
