Круг Таро, Рейки и Магии

I need a jacket for a return to office work, and the fitting room has become confusing. What looks proportionate in the mirror does not always feel comfortable on my commute. Adding length helps with comfort, but then I question the proportions of the whole outfit. I bookmarked personal style analysis as a starting point for naming what I am comparing. I am interested in body proportions and garment lines rather than a rule about hiding anything. Would you keep the trousers and shoes identical while testing different jacket lengths? My plan is to photograph both angles and record whether each jacket stays comfortable seated. Advice about shoulder seams would help too, since size labels have not been consistent. I would like the final choice to work with a backpack and ordinary walking shoes. How would you organize that experiment before bringing style-system terminology into it?
