I actually avoided doing this costume simply due to the fact that it's a really freaky mish-mash of Medieval, Renaissance, & Victorian fashion. (I get the feeling Joan Bergin must have been on crack when dreaming up some of these costumes, b/c she's constantly getting her time-periods AND the characters' visual personalities mixed up. Either that or she forgot what century Henry VIII & his contemporaries lived in).
Even this artistic imitation isn't accurate b/c the game lacks the floor-length outer sleeves on Anne's dress (a sleeve design used in the High Middle Ages, as that era was called), though I did my best. (I liked the fabric anyhow). The crown was difficult too. It looked like a tiny gold filigree screen w/ diamonds, & was re-worn & recycled several times in the series.
Anne wears this in 2 different scenes, & I chose the 1 where she's NOT having a fight w/ Henry & begging him to give her another chance at delivering him a son. Though it was sweet seeing her holding little Elizabeth in her arms.
