It makes perfect sense, each Shezow changes with the times
Aunt Agnes was 64 in presumably 2012 when the show was airing so she would be in her prime during the 70's and early 80's, so the thigh high gogo boots with elbow length gloves, cheetah print bodysuit are definitely the style of that time, 20's Shezow was a flapper and the rest are self explanatory (Cowgirl, Roman, Cavewoman)
Guy was 12 in 2012 so he'd be 21 this year. Coming into his stride he'd probably be a gym thot wearing things like Short Shorts, Crop Tops, Yoga Pants and sneakers, being a smug jackass that he is he'd definitely learn to enjoy the attention to the fullest.
TLDR: Guy should be a Dudebro Gymthot
