I personally wouldn't bother with any of the pink sets from sewers. What I found to work well is Drainers helm and armor to up your dodge and a Bagman's bow for the added damage. You could also go with a full Drainer set if you want the extra dodge or a full Bagman set if you want max damage, but I found that combining the two was the best of both worlds. This is only taking PVE into consideration and assuming you're full dex and not some kind of hybrid build.
