In 2009, Deanna Dahlsad (aka Pop-Tart) of Kitsch-Slapped wrote this refreshing corset-positive (or in the very least, neutral) article series in 3-parts.
In part 1, she discusses the “so-called medical evidence” against corsets – why their studies were restricted to subjects of lower social class. (Even though working-class corseted women were seen as more “robust”, they also had less access to healthcare and more exposure to infectious diseases due to their professions.) On top of all this, medical evidence against corsets still may well have been cherry-picked.
In part 2, the sex-appeal of corsets is discussed (and not in the way you might think). Irony: in the early 1900’s, corsets were thought to bring about sexually immoral feelings and behavior in women. Just a few decades earlier, any woman who was seen not wearing a corset was considered to have loose morals.
In part 3, she gives an overview of the suffrage movement and how many of these feminists kept their corsets on by choice. Why? Because they had more important things to think about, and appearances still matter in society. The “Shrieking Sisters” were ridiculed as being loud, masculine, obnoxious activists and many of the more peaceful suffragists were concerned that this radical behavior would hurt their stance more than help. If you saw someone dressed oddly and screaming in the streets, you’d probably think they’re crazy. Dressing well (including the use of corsets) was still a symbol of being a rational, respectable member of society.
All three of those articles have lots of links and citations, so you can get lost in a jolly time-warp about corset history. I suggest you read these when you have time to spare! The conclusion left me a bit unsatisfied – if one delves deeper, corsets have more uses than just leading to copulation, but the articles are still extremely well-written overall, and worth a read!
