Joy, that's a good point about nude colored straps. Visible nude straps feel much more 'underwear' to me. I wear black bras when the straps might show, and nude under white shirts. But now that I'm wearing a lot more white, I wonder if I should get a white bra too. I seem to recall that white bras show more than nude under tops? Not a huge concern for me, though.
I hope your rib heals quickly - that sounds like no fun, and must make bra try-ons less pleasant!
