Few of us can claim to actually enjoy bikini shopping. The stress of buying for a DD+ bust is even worse as it's not just a case of scrolling the net and picking one in a pretty colour, you have to look at support, coverage, hold, and whether you actually like the look, once all that is added in.
For us bigger busted ladies, flimsy triangles and bits of string do little to support, or hold in, the bust, and ones that come in dress sizes can just go straight out the window as they do not translate to bust size at all. Don't even get me start on those of us that wear a different size up top to the bottoms, as that's a whole other ball game.
