pet hate

Only when I started sewing did I learn that the vertical slit at the back (or side) of jackets and skirts/dresses is called a vent. Most people will know that the vent is often (always?) sewn together with a simple seam when you buy clothes in shops. It's one of my pet hates that people don't remove that seam when they start wearing the piece of clothing.

The button from the back of my new coat fell off the other week, and when I finally got round to sewing it back on, I noticed - to my embarrassment - that my coat has a vent. And it was still sewn closed...
