Bikini and swim shorts

The bikini is a gorgeous material and feels very soft on your skin. Unfortunately I don’t think it is suited to double DD sizes. I even exchanged a large for an extra large, but it is the back and neck straps that increased as oppose to cup size.
The swim short on the other hand is true magic. Comfortable swimming shorts, extremely flattering. Great for your period! An amazing discovery. But I suppose I can always wear my normal bikini top with the shorts, in black very versatile. Great for showing off my mid-rift!!
