What stage in the trend cycle chart does this item apply to?
Based on her casual outfit i would categorize her outfit to be at the stage of peak.
You do see a bigger audience around the age of highschool students, wearing this style more often.
Any of the pieces can come in various price levels and is more mainstream.
What fashion leadership theory applies to it if you were a stylist?
My styling technique would always depend on the clients style and age market. more likely this would be a high school students look. Casual hang out look wearing a basic graphic tee, skinny jeans, and moccasins. She added accessories wearing bracelets and a satchel purse. I myself personally would not put together this look but to style it up i would toss the shoes and throw on a pair of wide set leather below the knee heel boots. To jazz up her plain shirt i would add on some sort of quarter sleeved cropped jacket, more in the blazer family. something more specific would be a light blue and white discrete striped blazer. Hair up and a tote bag as a purse with a long necklace minimal jewelry.
