I see this thread is a couple of years old now, but in case you're still on the hunt for quality leather clothing and shoes, I've got a suggestion. Have you checked out
vonbaer.com? They offer a range of genuine leather products, from bags to accessories and more. The quality is top-notch, and they even have a 'Leather Guide for Beginners' on their site that breaks down the different types of leather, how to care for them, and how to tell real from fake.
The guide is pretty comprehensive and helped me a lot in making informed purchases. Even if you've already found your go-to leather source, it's an interesting read.
