(so let’s say the short dress she’s going to make off that fabric is 1/4s of her legs. which is 25% of 63, or 15.75. i’m rounding this to 15. since i’m lazy.)
(so five of those would be .75m and if we consider the top part to be roughly 2 metres- provided if she makes the cuts just right, she should have enough to fill out a single small dress using just that fabric (there’s going to be wasted space from having to spread out the cuts, after all)
(So in conclusion if I was Drakor i’d have bought either one or two more metres depending on my intentions for the dress just to be safe, accounting for space between cuts, fat areas on the body, etc etc.)
