My mom's tomboy style

My mom recently sent me some old family photos of our cousins, summer vacations, all sorts of things—but what stood out most was my mom's incredible style. She wore Wellington boots, flannel shirts and my dad's sweaters, and her pieces were loose and relaxed. Yet through her tomboyish style, she still exuded grace and femininity. I'm so inspired by these beautiful photos and am going to try to shop my closet to see if I can create some similar outfits. What was your mom's style like?
P.S. Having babies in Paris, and my mom on her wedding day.
