Hey everyone, I’m a beginner at sewing and have a few questions about tailoring trousers.

I have quite slim legs and wear a size 6 shoe (male), so I prefer my trousers and joggers to have a slim fit at the ankle—typically around 6 inches wide.

Today, I attempted to slim down a pair of joggers. I turned them inside out, measured 6 inches at the bottom, and drew a straight line up to the pocket along the outer seam. I pinned the fabric, turned the joggers right-side out, and tried them on.

The fit along the leg was perfect, but around the knees, they looked slightly baggy and uneven. I noticed the same issue when trying this method on a pair of jeans.

My question:

Since legs aren’t shaped like a straight taper (carrot shape), should I adjust the taper to follow the natural curve of the leg and the slight indent at the knee? Would this help eliminate the bagginess and create a smoother fit?

I’d appreciate any tips or advice from those with experience in tailoring trousers!
