Adding "well-tailored" as a qualifying adjective is effectively begging the question. A well-tailored anything will make you look better than its off-the-shelf equivalent.

If we're just throwing free tailoring around, I'll also have my polo and khakis tailored, and then we can compare between them on the runway. It may well be that no style of clothing makes me look better than a suit, and that I still don't look good in one.
