A friend (female) of mine who really likes what I've done with my own kilts wants me to make her a 'girl version' of one. So I'm gonna give it a shot with some very lightweight wool I got for an amazing price (it's too light for a kilt for myself I think, it's like 8-9oz wool).

She's not a big girl, but she has a VERY ample backside and hips. We're talking like a 48" hip measurement and a (if memory serves) 34" waist measurement.

The correct length from the front would be 18"... but if I do 18" in the back, won't it pull up exposing her rear?

My first thought is that the taper at the waist would take care of it, but then it would be very low in the back... right?

I guess my question is, if you take correct waist/hip measurements, and taper the 'kilt' correctly, can you use the same length all around without a problem? Even if the person's backside is very prominent?
