That's fantastic. I did the same thing after several trial and errors. Just sent in a pair of bespoke trousers and let Luxire replicate it, which they did a great job with.
As to your drawstring trousers, what's the fabric you've used? I wonder if the style is to casual for wool trousers. I envision that this style would look great with a pair of linen trousers.
I used This cotton linen canvas
I would say the style is definitely too casual for worsteds. You could probably pull it off for more casual trousers such as donegal tweeds or something with a pattern though. I can confirm that this style looks great in linen - just check out Informale.
