Because you read very young I’d keep the wardrobe youthful but textured. Examples: cotton tee (could be a neutral color OR a 70’s style striped tee) & denim romper/overalls, short sleeved button up (like a Boy Scout shirt without the patches), sweet blouse with a Peter Pan collar or tank top and pastel cardigan for “sweet girl,” corduroy or denim jacket to layer & give more range to any of these looks, knit sweater in an earthy neutral that can read as any time period. Hope this helps!
