Didn't know the buttons (those metal ones with the Peruvian and Chilean insignia) are not available for the public but on authorized dealers only. It was a surprise. Chose then to pick ones that have similar insignias in it but they are expensive as hell. I'm going another route as I have other options.
Then went to meet the wardrobe makers at Rimac district to show them how I want the soldiers uniforms to be with details. The cost was around what I expected.
It certainly was a long day.
Going back to Rimac tomorrow to finish uniform-making details.
