Lily's Caroline Dress by Mouse House Creations
The fabric is similar to a quilting cotton - a fairly thick and stiff cotton. I just used a sheet for the lining. This fit me really badly when I first made it, although I had done a muslin and made some changes - I just had no idea what I was doing. I went back later and made some further fit adjustments and it's better now. I'll make another one in a lighter material eventually, with a proper fit. The measurements on the pattern definitely seem off though.
