...but Jennie at the Sense and Sensibility blog wrote a post to end all posts on the subject. Go read that and then look at the nice collection of links I found for you, lol.

Baker Lane - lovely historical patterns
Sense & Sensibility Patterns - more lovely historical patterns
The Play Dress - fairly inexpensive play dresses
Garlands of Grace - some of the best hair wraps or coverings if you do that... even if you just need a headband these are awesome

I just finished making the Sensibility regency dress for Ana. After talking to a lot of people, her obsession with fashion and the tightness of her clothes just wasn't healthy, so we're sticking to girlish dresses and skirts.
