You spend a lot of money on a suit, wear it a few times, have it dry-cleaned and suddenly it just doesn't look, or even fit, like new. It's all in the pressing. Sam Cox knows a lot about pressing; his establishment has been doing it superbly since 1961. "First, we use no air-operated equipment that smashes clothes and actually creates wrinkles and shows seam impressions. Unlike most, our presses have cloth heads on both sides to prevent shine." According to Cox, it's all in the details. "If you set the collar properly, the lapels will fall properly, and there will never be a wrinkle between the shoulders in the back. And we never press with the pocket flap down, which can make an indentation that ruins the look of the whole jacket. We take the time to press the flap separately." You pay for what you get: Cleaning and pressing run $13.60 for a suit, $9.25 for a jacket and $6.60 for a pair of pants. Pressing alone costs 25 percent less. Cox's clients, including Neiman Marcus and the clientele of several of Dallas' leading custom tailors, agree that it's worth it.
