So dd(8) needs a new costume. I can, it seems, choose from splashback, actionback, spliceback, slickback, raceback, clipback and so it goes on.
What she wants is one that doesn't leave her back too exposed but one that is quite sporty and plain looking, so think Speedo rather than Boden. What should I be looking for? Is there any technical reason why the vast majority seem to have a hole at the back - do they fit better that way?? Any help would be much appreciated!
