Am I on the only person out there who absolutely cannot stand visible bra straps?! Everyday mishaps can happen... Everyone can be guilty of it at some time... But on an expensive advertising campaign (for an insurance company)? Come on! Ever heard of PHOTO SHOP, people?!
Some Russians seem to think that bras are intended to be seen... It's quite common for women to wear black or brightly colored ones under transparent shirts, even to work, even when teaching high school boys (haven't seen anyone doing that where I'm working now, though)!
