Clothes are shitty these days (M&S I am looking specially at you!), so I pretty much take it for granted that things will shrink after the first wash. With this in mind, I have at times cleverly bought a size bigger to allow for shrinkage.
Except this has backfired because tops shrink in length but not in width so I end up with short boxy tops (my worst shape), and trousers shrink in both length and width so I end up with trousers that are too tight on the thigh and much too short, to never be worn again.
WHY???
