I guess I'll go contrary to the group (though I would also advocate not trading the shirts).

I've flown through DCA 2-3 times recently with cuff links and I've set off the WTMD each time. My belt is the only other thing that I go through the WTMD with that has metal (just a normal belt buckle). The last couple months I've either taken to wearing non-cuffed shirts or taking out the cuff links prior to entering security.
