So I have decided one of my new pet peeves is wearing bras under tank tops with the straps completely showing.... that is, wearing a racer back tank/t-tank/halter tank with a regular strap bra.
I think this is super trashy. Either wear the right bra to go with it, or dont wear the shirt.
I also dont think wearing "clear" bra straps with those shirts makes it any better - I can still see your bra.
I do not think that having your bra straps slip out and be slightly visible while wearing the correct bra is trashy - those things happen from time to time.
I also judge you as tacky if you are wearing a shear type shirt with a colored bra underneath - why wear the shirt at all - clearly, you want me to see that you have a hot pink bra on!
