When did it become acceptable to have one's bra straps or more on display for the world to see?

I do not think that I am that old, but call me old fashioned on this. If my bra strap or the top the cup accidentally shows for a few moments, eh, no big deal. Lingerie is not something to be embarrassed about, but I do believe it is private clothing. Underthings belong under our clothing.

I do not feel it is acceptable to purposefully wear a bra with a shirt that does not cover it. I was hoping the trend of young women wearing spaghetti strap tanks with bras on display would be short-lived, but it seems to be getting worse. Recently I saw a lovely young women looking completely trashy by pairing a darling halter top with a strapped bra. Put on a strapless bra, my dear, or if you are perky enough and the shirt is not sheer, go without. Neglecting to wear underthings appropriate to your outfit is déclassé.

May the pendulum swing back to covering up lingerie again soon. Backless shirts need backless bras, thong sides and backs belong underneath the waistline, and bra straps belong inside of shirts.
