In the archives of Sweden’s Royal Armoury, from 1669:
Cloth of silver petticoat breeches – 22″ waist, with 56″ circumference for each leg. (Each. Leg!) Approx. 5 yards of 4″ silver lace around hem and along side seams, with an additional 16 yds of 1/2″ inch trip applied vertically along the hem (inserted into small slits in the fabric, under the lace). There are traces of old stitches along the sides where rosettes or loops of ribbon might have originally been attached. Two hidden pockets on interior of waistband, two large pockets along sides (though not on actual seams.)
Possibly worn with this?:
Mind. Blown.
