Mary’s front row ensemble looked just as put together as those worn by the fashion models.

If there’s one thing Lady Mary knows how to do, it’s wear a cranberry bowler hat. Breaking Anthony Gillingham’s heart, however, is not so simple.

Source: PBS

Mary's daytime outfits are always demure and polished. Every button on her blouse is buttoned and her hat is in pristine condition. But she stays true to her signature look with a long strand of pearls.

Source: PBS

Downstairs, Daisy and Mrs. Patmore keep on their kitchen caps and aprons, while Mrs. Hughes tends toward her functional all-black dress.

Source: PBS

The distinction between Violet's lavish style and Isobel's reserved style is obvious, especially in the many moments where the two women disagree.

Source: PBS

We love how the embroidery detail on Mary's dress complements the architecture of the bench and staircase. Shots like this one reveal how intricate the style was at Downton.

Source: PBS

We love this graceful moment in the rain, when Mary makes her way from the hotel to the car in a furry-embellished day coat.

Behind the scenes, Michelle Dockery and High Bonneville take a stroll around Downton in their modern day puffer coats.

There's never a dull colored moment in Downton, and that's what we love about the TV show. Cora's printed gown matches perfectly to the wallpaper in the room. Elizabeth McGovern's behind-the-scenes accessory? An iPhone, of course!

This shot is all about the draping, from Mary's strand of black beads to Cora's chiffon sleeves.

For a hunting trip, Lady Mary tends toward her movable suits and a simple day hat. In the 1920s, that’s a matching plaid skirt and double-breasted coat. We bet she appreciates Lord Gillingham's ability to match his separates with his newsboy cap.

Anna, Jimmy, and Lady Rose show off their best for a day away from Downton. Of course, the ladies tuck away their locks in their complementing hats. At Downton, it's all about the accessories.

For an evening soiree, the men complement their sleek suits with white bow ties, and Lady Mary piles on the jewels. She always contrasts the details of her gown with an embellished headpiece and a long, eye-catching necklace. Now that the Crawleys are heading into the roaring '20s, Mary often knots her pearls.

Before Matthew's death, he and Mary made an impeccable couple. He even matched his tie to her cranberry separates. Time and time again, the pair appeared as though they were a match made in heaven.

Martha Levinson's visits to Yorkshire from the states make for some of the most hilarious episodes. It's clear from her fashion choices — just look at that furry coat and lavish hat! — that Cora's mother is ahead of the times. Each time she visits, she can't help but mock Violet's resistance to change.

Lord Grantham, Matthew Crawley, and Tom Branson show off their crisp white athletic wear: casual polos and cream sweater vests.

Mary's was nothing but elegant and graceful in her traditional long-sleeved wedding dress and complementing veil.

Lady Rose MacClare and Lady Edith match the sashes on their caps to the rest of their outfits. Lady Rose, of course, made a statement in bold blue, while Edith kept things neat and clean in peach.

Despite Lady Sybil's eagerness to break away from the everyday life at Downton, she never appeared in anything less than appropriate, opting for loose, whimsical silhouettes. On the day of Lady Edith's wedding, Sybil and Mary were matching in pastels.

Michael Gregson, Robert Crawley, Matthew Crawley, and a couple of statesmen show how spiffy they look in their suits and caps.

Leave it to Cora and Edith to master the art of breezy daytime dressing for an afternoon of leisure.

Matthew and Lady Mary always knew how to dress for a fancy evening. When Matthew returned home from war, he sported his military jacket, and Mary attracted all eyes in a striking black gown.

Mary was, both literally and figuratively, between men when Sir Richard Carlisle came to visit Downton. We love how that becomes clear in her dress, too. Her plaid look stands out against the neutral tones Richard and Matthew are wearing.

Lady Mary never let Richard take her for granted. She stands her ground in a bold, beaded dress, too. It’s obvious that costume designer Caroline McCall has chosen black as Mary's power color.

Actor Allen Leech keeps things neat and tidy before he shoots a scene as Tom Branson.

Hugh Bonneville's bow tie must always be cinched perfectly at his neck. We know we'd never see Bonneville as the Earl of Grantham with a crooked accessory.

Violet Crawley and Lady Edith always seem to be on the same page, and we love how their outfits make that clear with subtle similarities: both women wore leather gloves, patterned hats, and teal details during a scene from season two.

Source: PBS

When Lady Sybil decides to become a nurse, she must obviously look the part. Here, a couple of costume staffers make sure actresses Jessica Brown Findlay and Michelle Dockery are in perfect shape to look their parts in the early 1900s.

Actors Brendan Coyle and Joanne Froggatt get ready to play John Bates and Anna Smith in their more fancy attire.

A dinner at Downton is the perfect excuse to gaze longingly at the striking detail on all of the evening gowns and, of course, the shimmering jewels.

The women and their father, Robert Crawley, open their home to a crowd. Sybil, Edith, and Mary show off their "working attire," which always includes full skirts and functional flats.

Sarah O'Brien, Gwen, and Anna show off the typical attire worn by the lady's maids downstairs.

We love how Lady Edith makes the most feminine dresses look natural. Seeing her next to a row of flowers is just the icing on the cake.

Lady Mary's top hat, complete with netting, is everything. From the very first season, Mary's fashion choices made it clear that she's a force to be reckoned with. She can pull off the most daring looks with ease, and when it comes to riding a horse, Mary's practically one of the guys . . . in a very spiffy riding suit.

This simple shot of the Robert and Cora makes such intricate daytime wear seem so effortless. And perhaps it is for the couple, who have quite a lot of help getting dressed.
