I would like to make one or two tailor-made suits for myself. I would like to find a place that has a good cost-quality balance, something in the range of 400-700CHF per suit.
Any suggestions for the Geneva area? Are there cheaper options in the France Voisine?
As people have said above, bespoke suits at that price range can only be found in asia or on websites like Hockerty.
Hockerty is cheap but it reflects both in their materials and their tailoring.
For that price range I would suggest Suitsupply or Spier & Mackay and then have adjustments made. ( Black Lapel seems to be decent as well but I've never tried and can't comment)
Get a local tailor to make final adjustments at the end of the day and you're set.
If you do want to go the bespoke route, I can recommend these guys:
