Well, 34C is starting to get up there in size. My g/f is 38C, so I'm going by what I've learned from her 🙂 Something with an underwire would be more "supportive" so to speak. Something strapless just won't hold things in place quite as well. Also, when you start getting up there in that size, the push up bras and wonder bras start to give you cleavage that you could get lost in.
You could go w/ this.. Get it w/ the hearts for that valentine day appeal 🙂
