Am i wrong

ok i got the Big Girl Knits book from the library so i can knit something for my mom… well i am loving the “Yo! GaPants” and the “Natalie Coat”. well i could prolly find something like the coat but i have never seen the pants knit up and would love to make some…only think is the pattern only comes in L 1X, 2X, and 3X… i’m maybe a L but plan to lose the rest of my “baby fat” :eyebrow: so i was wondering how to make a M in those pants and possibly the coat…? :?? any ideas?:flirt: i could prolly get away with making the L in the pants and just fit them to my waist… but the coat is way over my head!
