Anne Bulleyn (or Boleyn as she became known) was a commoners' daughter, and as such, would have had to wear the same blouse frequently, especially in a time where even the rich only had a few. The average for the middle classes was 2 or 3.

Separate sleeves and slashed sleeves were a fashion item, because it showed off the fine linen shirt underneath. People were wearing and making gowns with sleeves set in as much as 800 years before Henry VIII. It was nothing to do with washing, as anyone who has ever washed socks will tell you - one always disappears.
