I just got the green jacket (Astral) and am a 34 D...I love it.
I was having trouble with other vests due to pocket placement but this one is fabulous. Pocket ends up high cleavage (which doubles as great coverage) and I haven't had the side boob issue with it...bonus for being higher MIDDLE pocket actually made self rescue easier for me than my previous vest having pocket below the nipple on one side only. But then again it was made for kayaking flatwater not for launching boobs plus a pocket full of essentials over the tube of a raft...teehee
All of this is subjective though...my suggestion is to go into a retail store in your wetsuit or hydro skin or whatever gear you wear and physically try on some vests and then move ALL OVER in them. Do a quick inverted yoga flow if you want (I promise the store folks have seen odder things) just to check out how your boobs move (or DON'T) and whether it feels right or constrictive.
And BTW that was hilarious with the guys asking for pics...learn to love the mild harassment and view it as a compliment toward the fact that you have boobs and they like boobs or this will be a short visit to this industry for you
