I have 1 economy and 2 standard, and my kids have 4 thrifties. My first was an economy just to test the waters of kiltdom and I loved it so much I just had to see what a better kilt was like so I got a standard and liked it even more. I just ordered a thrifty yesterday for a "throw something on quick" kilt (equivalent to sweatpants) but other than that specific need, I wouldn't get less than a standard again. Even though it's twice the price of an economy, it's twice the quality and then some. I haven't noticed much difference in the economy and thrifty as far as quality goes. They are basically the same except one has buckles and loops and the other has velcro.
