Have you ever tried to put on your seatbelt only to get frustrated by all the loops you have to unloop? Or you just say fuck it and drive with the discomfort of a partly turned seatbelt pressing against you. Well, bra straps are like that too actually. Except that you can't reach the back and there's too much elastic to get a strong hold on anything. And of course, you can't fix it in public. Maybe I just buy the cheap ones, thinking that price couldn't change utility. Maybe they screw up the cheap ones on purpose.
