Someone with Tomboy Style, in my iconography, dresses like a Sturdy Gal, but cool. Tomboys use the strength inherent in Sturdy to make sure a Gal never gets misused. They are comfortable in their skin, albeit a skin with extra-credit earning eye for design.
The photo at top is of women at Vassar in the early 60′s. My aunt, who provides me much of the inspiration here for Sturdy Gal style, graduated from Vassar in the late 50′s and went on to raise 3 boys, ski fast, ride bicycles through France, and put up her own boat-patterned wallpaper. The blog cheers me, rather a lot.
