The bustle of the 19th century made sitting a challenge. Thus the genius of the spring-loaded Langtry bustle. It collapsed, accordionlike, when a lady sat. When she stood back up, the bustle automatically sprang back into place, inspiring James Laver to declare it "one of the most extraordinary inventions in the whole history of fashion."
For today's women with silicone buttock implants, the sitability question is just as pressing. How does one sit when one has silicone appendages on her backside? Very carefully, apparently. As one poster on a blog about plastic surgery recently observed, the prudent implantee should be cautious around cacti.
