I employed the smooth waistband technique I mentioned before. I find the wide, firm elastic cut to the exact measurement of the waist at that point to be more comfortable than thinner elastic cut with negative ease.
I cut the shorts pattern from the pants pattern, but flared the leg hems just a little.
The fit is slim (hence the use of lycra) and there is a very slight bootleg cut.
I love these - the fit is closer to what I wanted than what I got from the BurdaStyle download Corinne Yoga Pants.
Pattern: Jazz Pants (Ottobre 1-2008-5)
