Agreed, Karren, I also never buy online, with the exception of Ebay, where I can ask a seller for specific measurements. While it's fun to try things on at the store, I realize that few of us get to that point.
In response to a thread back in October, I posted a fairly simple guide to how anyone can easily shop for clothing and shoes in any store you choose, and be confident that the items will fit. Using this method, I haven't had to return anything in years. The only real catch is that you have to have the courage to browse the ladies garment section in whatever store you go to. Your choice. Buy online and hope it fits, or screw up your courage and go to the store. If brand name stores scare you, start with thrift shops. Quite often many of the items there are new, some still with tags. And, let's face it, most of us are not of the age where we're chasing the latest styling trends. Take the basic styles, available anywhere, and learn to accessorize to keep them up to date. And, if your wife sews, she could take that knee-length skirt you found in your color and material, and turn it into the miniskirt that all us 60+ year-olds just can't live without.

Actually, second-hand stores offer a much larger variety than chain stores. and give you much more opportunity for creativity. Chances are, you're never going to even wear out second-hand clothes.
