I had that problem 2 years ago
. . . get some of the big men's clothes - my Dad is 6' 7" and used to be heavy so I got his 5X shirts out of the closet (hubby is the same size I am
). . . hit a thrift store after the racks are restocked. I also hit Name Brand Clothing a 1/2 of 1/2 outlet store. Just inspect what you want closely - some garments are not wearable (tear, rips, or stains). . . but I was able to get 3 good pairs of pants for $20 !!
