This is a little less, um, exciting than either of her older siblings (Autumna and Winter); most of what Summer wears is pretty utilitarian.
She’s in college - Summer is based off of my memories of my first 2 years of college, so, like me, she’s a theater techie at a medium-sized state college. She probably does some work ON stage as well and, while I haven’t decided what her major is, she does some work in art, maybe a minor (She does like her big sister, after all).
Summer’s clothing consists of jeans or jean/khaki shorts, Keds or sandals, and graphic t-shirts of the fitted girly variety, with baggy sweaters over them in the cold of winter. Her main hairstyle consists of pulling her long blonde hair into a low ponytail.
Most of what she owns is paint-splattered, except her “good jeans."
And yes, sometimes she claims Winter’s old dress shirts.
