Which part of the fabric is wearing thin? Is it the pants? If so, I’d recommend that you buy spare pants (if possible) for future suits and spread out the wear. (So the pants are worn less 1 every two weeks.)

This link has some good advice for getting wear out of your suits. Counterintuitively, one problem is that “finer” suits (softer wool fabrics with high ‘super’ numbers) are going to wear out quicker than lower super numbers.

I’d guess that the reason your Chinese made Perry Ellis suit outlasted the Suitsupply suit is likely because the Perry Ellis suit is either made of “cheap” but sturdy wool or is at least somewhat synthetic.

How often do you spread out the wearing of each suit? What’s your definition of ragged? Where did you get your current suits?

You can get a Macys suit or spend $1500 on a MTM suit either one will still going to be worn out if you wear it too often.
