Delayed reconstruction can look quite nice if done artistically well by a high quality team. There are many examples that you can see and, as you'll note, the end result depends in part on the starting point. See here for basic delayed DIEP outcomes, go to photos that show an empty chest in the left side frame as they represent "delayed" reconstructions........
and here for more extensive presenting problems that required elevated levels of technical problem solving.......
Hope this helps,
