I use underlining in many of my finished garments. Sure, it means one extra step, but it’s what gives couture garments a superior appearance. I like adding an underlining because it adds support, it increases the longevity of the article of clothing and they wrinkle less.
I’ve included a great video by Gretchen Hirsch where she talks about underlining. I hand baste my underlining to my fashion fabric and then sew by machine.
I normally don’t underline knits, But I plan to change that with my next sewing project, which is another knit maxi skirt. I’ll have to purchase some underlining knit fabric after Christmas. Hopefully, I’ll catch an awesome sale. I’ll be sure to post pictures of the project.
