I am all for priests refusing Holy Communion to inappropriately dressed women (and men if that is the case). If you're in Church, we don't need to see more of you than your husband does. And if you have to squat or bend at the knees to kiss the icons you know your skirt is too short. It's all about moderation. Because for all the bare shoulders and creeping skirts, there is the other extreme in modesty. Being modest does not mean you have to look like a bag lady.
(Oh BTW, SrbMama, I don't know about other parishes, but the only women I ever see dressed to the nines and in 6" stilletos are the Russian emigrees. Those women are amazing. I can't make it through 2 hours of Liturgy in Birkenstocks but they can stand and hold babies on their hips in outrageously high heels.)
