That is one thing few historical movies or TV series take into account when trying to be accurate: The dirt and lack of personal hygiene. The bad teeth (a major cause of death), and breath etc. In the Tudors, everyone looks freshly scrubbed and perfumed and have great teeth. That's OK, it's still a highly entertaining show.
If I haven't said enough bad things about
The Tudors already, here's another one.

What I have seen of the costumes--you can buy reproductions of some of the costumes from Museum Replicas--especially the men's costumes, look incredibly cheap and cheesey to me.
Accurate Historical Spoiler. ...Sorry, I can't help myself. ...

For anyone who may not know this already, it was Henry VIII's younger sister
Mary (not
Margaret) who was sent off to France to marry the elderly French King Louis XII. Mary subsequently married Henry's friend Charles Brandon, duke of Suffolk. Mary's granddaughter was Lady Jane Grey.
Henry's
older sister Margaret had been sent off by their father, Henry VII, to marry the king of Scots. It was from Margaret Tudor's marriage to King James of Scotland that Mary Stuart, aka Mary, Queen of Scots, derived her claim to the English throne.
