Angie's comment on Tanya's post highlighted a topic I've been thinking about since the warmer weather arrived here. What are the "modern" guidelines for showing cleavage? What about bras? Can they just be one more element in an outfit? What about bra straps and tank like tops?

I bought the Caslon shirt dress in super bleach recently and like how it looks unbuttoned a bit. I thought a sliver of bra might be ok to show if it gaps a bit when I move. What do you think? I would be tempted to wear a white bra because the dress color is so light. Would I need to get a bra in a different color to show it is done on purpose?
