Hello! I need some advice on how to alter these pants, any tips or do on how to make them larger? I’m fairly new to sewing.
I found these cargo pants this summer on a second hand and I could just get them on me! So I brought a second pair of similar fabric so that I can make them bigger.
Ive added a few pins on where I plan to make a dart as thats the only space with no pockets that go down the tights.
I think I need to add around 6cm by the waist and 3cm by the hip and then I’ll let it taper down to the knee seam. Does that sound like an okay play?
Here are some more pics that are overly bright since the pants are black:

Yes, it’s called adding a gusset - that search term should get you some videos but you’ve got it pretty much right. Long thin triangle inserted hopefully somewhere there’s currently a seam.
Oh, a gusset. Thanks! Then I know what to search for. I’ll check some videos as you suggested. I think the hardest part might be to measure how much I actually need to add and to make it even on both sides haha
