How to sew a Finnish Viking Eura style under dress, by Mehloic. It's in swedish, but use google translate, or in short, you measure your arm length (throat to thumb), wrist, and the base of the sleeve (one hand down from your collarbone to top of shoulders x2), mark it from the middle on a folded fabric, this is the blue bit. Then you extrapolate those lines down to the bottom of the fabric so you get the pink bit. Then sew it up as per the picture at the bottom. /vanityfairy
