This is a simple and plain Victorian cotton day cap, such as in this Victorian painting or this 1855 painting. ‘This shape is particularly liked by the poor, from the ease with which it is made up and washed, as, upon undrawing the string, it […] lies quite flat to be ironed.’ (The Workwoman’s Guide, 1840)
It’s made with white cotton batiste.
The day cap is completely handsewn.
It is gathered with a string.
It’s quite easy to iron as it lies perfectly flat, when the back of the cap isn’t gathered.
Here are close-up pictures of my handsewn day cap.
