10-year-old suits worth having tailored?

I purchased 1/2 dozen suits about 10 years ago. My plan was to have them tailored after I lost 30 pounds. I finally found the will power to lose the weight--I should be there in about 30 days. My question is are these worth tailoring or should I just go buy new? They are all traditional blues and grays. 4 are 3-button Joseph Abboud's bought at Nordstrom's for about $500 on sale. Tags say made in the USA of imported fabric. I also have a two-button that's the same, except for one less button. The last one is a Hugo Boss that retailed for $750, and was on sale for $500. Judging from the pinch test, I think they are all half canvased. They all have pleated pants.

I'm 6'2", 215(athletic build) and 49 years old.

All comments/thoughts appreciated.
