Giorgio Armani women’s brown linen pants size 38 us 2

These brown line pants are by Giorgio Armani and are size 38 which is a US size 2. They do not have pleats and measurements are shown in pictures. The only flaw I can see is that there is a button hole inside (behind the zipper) but there is no button. I don’t see evidence there was one there but why would there be a button hole? Excellent gently used condition.
