I have a viscose shirt that I absolutely adore...for the first two hours that I'm wearing it. Over time it stretches lenghtwise. By the end of the day the hem is two inches lower than when I began. (Under_petticoat_rule has confirmed this.) This wouldn't be a deal-breaker except that the V-neck is also two inches lower and exposes the entire center of my bra. Are there any options to keep it from stretching, or should I resign myself to wearing it two hours a day and no longer?
