I have the hardest time using patterns anymore. I have given up buying them.And I used patterns for 40 years.
I ran into a lady in Walmart about a year ago who told me about someone who made patterns just for larger women, You know I lost the name. The only thing I remember is the last name was something to do with sewing. LOL
I stick to my farmers dresses one size larger than the pattern says I take and pants I can find that have tie waists.
Good luck . Sewing for yourself can be fun.
