I bought a couple pairs of Ralph Lauren chinos and on both pairs, the buttons on the back pockets are coming off. The first pair, it took a few washes, but on the second pair, the button started coming loose after the very first time I washed them. Is this a bad batch or is Ralph Lauren's quality control always this bad? They are the "prospect pants" for those interested. I actually like them quite a bit, except for the button problems.
