You can make a ton of money by sitting in a bar and listening to a group of women express their grievances to each other, and the extents they would be willing to go to remedy said grievances and then solving that problem -- uncomfortable bras are one of those frequent topics. Personally for my working wife and her group of nursing mother friends, they would pay almost anything for a convenient breast pump without all the hoses and tubes (just in case anyone is listening out there ;) )
