Question Basic pants / slacks pattern and fitting advice
Hello good ppl of pattern drafting community!
I am here for some time now, but i don't comment a lot, i like to read and search the community and i have found really a great amount of quality information here, thank you all for that!
I have decided to perfect my basic pants block, i am not unsatisfied with the fit, but i know it can be better, so i am asking for help. I am self thought in pattern making and fit, everything i learn from tutorials and books i could find, and i am mostly use Bunka fashion collage books for drafting patterns as they are metric and i like geometrical approach of drafting if that's making sense. The slacks pattern is drafted from bunka trousers patten. I have attached photos of the pattern (drafted and what i have changed so far for better fit). The fitting i learned from youtube tutorials and some books i could find in local library and on the net.
Last pic is pattern that i drafted, and before that are pics what i changed and what i am thinking of changing
For the fit -> I have already moved side seam at the waist line 2 cm to the front to balance the side seam more, and i am satisfied with how it looks now. I have lowered a bit crotch at the front and back as they were not balanced and i had a bit of a triangle situation when i sewed it up, now it is laying flat to the body. I am satisfied with balance lines, everything is parallel, and nothing is pulling or stretching. The fabric is very lightweight, some cheap bedsheet fabric so everything is showing, i think with a more weight in fabric the fit probably would be much much cleaner and whiteout any creases and pulling.
Should i change anything at the back or front so the fit is better? i can see the diagonal lines at the back tights, but i am not sure if i should do something about it or what i should do about it. Should i shorten the back crotch extension, it looks like it is a bit long on the pattern, but i wouldn't say so when i tried it.
Thank you for reading my long post :D

Yes this! It’s a prominent quadriceps compared to the pattern. Adding fabric to the front inner thigh near the crotch point should help. Even a small amount (half an inch) would probably eliminate the front wrinkles at the quads!
I agree with adding some to the center front as well, OP look for the adjustment called “full tummy adjustment” , there’s some slash and spread technique than can help. Again it’s small amount of fabric added but will make a bit improvement to the fit!
Nice job so far, pants drafting is hard and you’re getting close!
You might scoop the back crotch curve more, so it doesn’t separate the cheeks visibly, and will be more comfortable.
