Welcome;
One needs several (read 'many') Kilts. People at my supermarket like to guess which one I'll wear today. They even have favorites! After all, wearing a powder blue Tux each day would get a bit dreary to others; They's wonder if you ever washed it, or did you sleep in it etc.
Stilwater has some quite presentable Thrifty Kilts - if you're strapped for cash, about $30.00 each. "Standards" are about $80.00 . that would give you variety until/if you want to spend a fortune later for a Woolen "Tank" .
