I vote #2 for the earlier round and #3 (LOVE!!) for pref.
A friend of mine has #1, and while it's pretty, it doesn't have a ton of structure to it and might be a pain to wear. It also looks a bit short on you. If I remember correctly, it has detachable straps, right? If you decide to wear it, consider including the straps because they will help with the fit issues in the top part
Also safety pins are your friends!! And a great strapless bra of course.
