I will start with the youngest :
16 years Girl : Grade 10, 5'7" wears skinny pants ( one pair of dark wash , burgundy, taupe - typically with spandex ) no flares or boot cuts. Does not wear jeans per se. A couple pairs of yoga pants with flairs and a couple pairs of thick tights to ankles. Wears flat shoes, vans or keds.. usually colored. For tops... typically something over the butt- flowy but not past the crotch.. longer - or a hoodie. Will not wear tops with names on them- except for a school or organization- nothing with AE, AF, Gap or anything at all obvious about the manufacturer. No Name brands.
18 year Boy - 1st year university : 5' 11" Will wear jeans or khakis.. typically straight jeans. One distressed pair. Khaki's or straight leg sweatpants or Bauer pants - blue and two navy. Again - no name brands. Will not wear anything that shows what it is. Will wear Uni sweaters, some graphic tees, plain tees with V- necks. His shoulders are large and he tends to wear a Men's medium to show them. These are fairly tight to the chest and then tucked into pants. Has to dress for hockey and wears dress pants and sometimes a suit- always a tie.
26 year - Girl- Working in Office, Engineer - A Kibbe Soft Classic. Looks fantastic in flared and gathered suits, high heels, sweat sets. Curvy- wear clothes close to body- 5'7" but typically in 3 " heels. Always waist emphasis, small belts- not wide. Wears short curvy fitted blazers- very few pants- some skinny types- no jeans. At home - wears yoga wear/ fitted thermals etc...Her clothes would make me look like Queen E. but they suit her.
28 Year- Girl - Working in Office - 5'8" - never wears heels, very curvy but wears a straight line. Wears jeans with flares or bootcut. Wears everything low rise. Zero waist emphasis- Kibbe FN? but with moderate shoulders and large bust. De-emphasizes body- for office. Wears name brands but not out front. Nothing flowy like EF , no gathers, - or openly feminine.
