From e-bay description:

" This auction is for the vintage authentic tartan KILT ... likely from the 1950s or 1960s...
The waist, with the buttons buttoned ..."

Buttons? on aprons?

"and the leather tabs hooked measures measures 13 inches across, laid flat. ... It is very nicely pleated in the front and smooth in the back ..."

Pleats in front? in that case the buttons are on the back.

Actually, it looks quite a good weathered Gordon kilt.
