So why, pray tell, have you surmised that the OP is tasteless and is devaluing herself by wearing a tube/tank top? Call me dense.If you look good in them, why not wear them? I think it IS valuing yourself to have confidence that you look good and feel good and can be yourself. It's not valuing yourself to hide your assets and try to be inconspicuous.
There is a middle ground between inconspicuous and tasteless. Bodies have surpassed brains in terms of value for many women. It does not empower women to be praised only for their beauty and bodies. It devalues them, and it devalues women as a group.
