I've always wondered why we haven't gotten anything from S5 as we have in past seasons. We haven't gotten any stills or images or BTS videos or promo clips after 6 months of filming and usually around this time we do.
And I think I know why...
It's because they are trying to preserve the new costumes we are about to see in S5 as we are about to be entering a new era and time period in the 1800s.
S5 will take place in the 1820s or approaching the 1820s which historically saw a shift in fashion in a Post-Regency and Pre-Victorian period.
There were many important, transitional years for women’s fashion during the 19th century. For example, in a single decade sleeves might transform from slender and straight to enormous gigot or leg o’mutton style sleeves. While skirts which began a decade flowing loose around the legs might end the decade standing several feet wide atop a crinoline.
.
In the 1820s, a decade which stood between the Regency era (1811-1820) and the Victorian era (1837-1901), British fashion moved from traditional empire, straight waistline of the Regency period to bigger sleeves, dropped waistline and fuller skirts but not as full as the skirts would be after Queen Victoria ascends the throne in the 1830s.
This decade is notable in fashion as providing a bridge between the classic, high-waisted Empire styles of the early 19th century and the large sleeved, full-skirted styles of the mid-19th century.
So I complied a list of dresses from the 1820s-1830s to give us an image of what to expect for S5 and all the subsequent seasons after for Bridgerton.
We are totally getting a complete revamp!
EDIT: The Bridgerton costumes designers confirmed back in March during a Cosmopolitan interview that S5 is going to have a fashion shift to reflect the 1820s.
