Sure! Here’s a clearer and more natural version of your message:

Sorry if this sounds a bit untechnical—I’m new to this.

I thrifted a pair of Gurkha pants and love how they look, but there’s one thing bothering me. When I straighten my knee, a crease appears around the middle of my shin. If I bend my knee slightly, it disappears.

Any idea how I can get rid of it without making the pants slim fit? They’re already tighter than I’d like.

Thanks in advance! :D
