Hey all, quick questions.

Main one is I have 4.3 yards of polycotton blend, 60% poly 30% cotton (plain weave, it was $4 a yard). The selvedge has about an 1/8" fray on it till the finishing occurs. Think I should leave this on, trim it or hem it? If I leave it on, do you think it would look skirt like or unfinished?

Question 2: Waist is 39.5, not snug but not loose, rounded up to 40. Bum is 42. Fell is 8. Does this give me enough taper or should I add more to the bum?

Thanks in advance.
