I took pretty long, I ordered April, 7th and received the pants yesterday. But the quality is so outstanding, I don't mind the waiting time.
Yes there's elastic but it's hidden in the waistband so there is not a scrunching that occurs. the only place where someone would notice something is right at the sides where the buttons are for the elastic band and it's a pretty small % of the total waistbank real estate so to speak.
The excel spreadsheet method is the one I've espousing for both pants and shirts after I used it for my first pair of pants. It works...period. It is an investment in time upfront though so be forewarned. Once dialed in, it's great and increases confidence in ordering more expensive trousers.
I'm not sure I like the area marked in the pictures above. While Ambrosi pants look natural the Luxire one doesn't. The arrows show, in my opinion, that there is too much fabric used to create the pleats. In this way, a rather flat rectangle (square) is created. Can anyone see it too? Other details are as always perfect but I'm not sure about this pleats. I wouldn't like every pair of single pleat pants to have the same look in this area. I suppose it was created because of the belt loops being placed in the same place as the pleat.
Nobody mentioned it before so maybe it's just me
