Hot boba latte in hand and AH answer written, I'm ready to tackle the discussion of Outlander's costuming that I promised @vintieguidebook!

So, as I discussed with #Bridgerton , there is a trend of costuming with anachronistically bright fabrics and imaginative costume designs to create a kind of heightened fairy-tale "this is not accurate" feeling for a movie.

There's also a trend of rough, gritty, dark costuming used to show realism and (purported) accuracy. Game of Thrones, for instance, used this to give a sense that its completely imagined fantasy setting is the true image of feudalism.

Outlander is another entry in this latter category. Costumes are typically made of dark wool or leather, which emphasizes the idea that Scottish life was rough and dangerous, with even lords and ladies of the Highlands choosing practicality over luxuries.

In the first season, Claire frequently wears jacket/petticoat, combos which read as practical, because today separates are a way to create more outfits. In 1740s Britain, looking like you had a lot of different outfits was not such a concern, and gowns were way more common.

This jacket stood out to me because lace-on sleeves were not worn in the 1740s - but to us it reads as Old Timey (associated with the Middle Ages/Renaissance, where it is closer to accurate) and, again, practical for switch-out-ability.

In the famous dressing scene, Annette Badland ties a padded roll on Claire to hold out her skirts. This reads as a homespun way to achieve something like the fashionable silhouette, but in the 1740s most women relied on their underpetticoats alone for filling out.

(This is the fashionable skirt shape at the time. Women either wore the hooped petticoat necessary to achieve it, or accepted that they couldn't. Hip rolls were worn in the 17th century, and false rumps in the 1770s and 1780s.)

The wedding dress is a really interesting case. For the show, it was decided that this should be a French court gown. There are some inaccuracies in the cut and construction, but you can really see how this was used to make sth very different from the other costumes on the show.
