Anne's Green Damask

Joss Stone wears this on "the Tudors" (season 4 episode 3) when she is with Elizabeth at Hever Castle and they are surprised by Henry VIII. The sleeves and the bodice mainly consists of dark green velvet while the petticoat and the cut-throughs are of an olive green damask. The neckline has been decorated with pearls only interrupted to show of more of the precious damask. At the centre of the bodice a very large square brooch with a topaz at the centre has been pinned to the stiff bodice. Besides the topaz there are four small pearls at each corner and a drop pearl hanging from the brooch.

Accurate Anne

Elvi Hale wore this gown as Anne of Cleves in the BBC production of "Six Wives of Henry VIII" from 1970. From the look of it BBC paid a lot of attention to getting the dress as historically correct as possible. And if you are wondering where on earth you have seen this dress before then take a look at the official portrait of the actual Anne of Cleves.
The rich red fabric is quite possibly velvet. It is mainly the amount of gold on the dress that indicates Anne's new status - notice the odd pattern at the edge of the sleeves, hanging from the waist and surrounding the bodice. The high waistline (we would call it an empire cut) was not used in England at this time which just added to the "strange" look that Anne is said to have portrayed. Also, it is very rare to see a noblewoman of this age wear a belt since it was not a part of the common attire. Another thing that sets the dress apart is the lace-work above the neckline that ends around the choker necklace. An Englishwoman would normally just have bare skin.
Besides the large amounts of brocaded golden fabric Anne also wears three necklaces: two heavy gold chains and a choker with a cross pendant. From underneath the heavy sleeves the frizzled chemise appears with its white fabric.
And then there is the hat. Unfortunately, I do not know much of German fashion during this particular time period so I will let it be up to your eyes to describe it.

A Different Style

Joss Stone portrays Anne of Cleves on "the Tudors" in which she wears this gown. It is different from other gowns on the show because Anne is wore German clothes at first which had a completely different style. The bodice is made of vertical stripes of moss green and purple with golden patterns (the one in the middle looks a bit like an elephant..). The dark green sleeves are not just very voluminous but has been cut open to show the arms - the openings are trimmed with braidings.
The neckline really stands out with its thick golden braiding from shoulder to shoulder. Instead of opening up to reveal a petticoat, the green skirt is completely closed; a piece of cream fabric with roses makes up for the "missing" petticoat. It almost seems as if the golden chain with the green emeralds has been sewn into the dress. The entire mixture of fabrics and patterns must have seemed very strange to the nobles at Henry VIII's court.
