Hi, I’m planning to buy the Lululemon Align leggings with pockets and with the front seam for my girlfriend. She is around 5’3’’ and 42" hip and around 35" waist measurements. I think the leggings will be mainly used for light activity and also lounging inside, so I think a relaxed fit is more suitable than a tighter fit, especially for sitting compared with standing. Based on this I’ve read that it is better to stick with the sizing based on the waist measurement, which will be 14, If I’m correct, instead of focusing on hip size, which would be more around size 12, with length 25"?
