She might consider building the dress around a tartan corset...I've seen a couple of shots on the internet where that was done. Our august innkeeper, Pour1Malt, has posted photos of his and Emma's wedding somewhere here on Xmarks and Emma's ensemble might serve as an inspiration for the young lady.

I would personally love to get a tartan corset for Mrs. Argon but it would, I fear, be something that would be relegated to the closet and never worn...oh well...

Best
