You can rent neckties now. I don't think it would be a good value for me since I tend to have shirt/tie/suit combinations that mate for life and always feel funny the first several times I wear a new tie as my brain slowly convinces itself that this was a good idea after all. On the other hand, it is through taking risks that we learn what works and what doesn't. More to the point, it's probably cheaper to get designer ties on clearance, especially since you can easily get several years out of the life of a necktie.
