ESO Fashion
This is a real good guide to fashion in Elder Scrolls. They have crafting guides for blacksmithing, clothing and woodworking. They also have pages that show good visuals of all the racial styles in light, medium and heavy crafted armor sets. A must have when trying to decide what you want your gear to look like. Players have also posted customized sets and tell you what each piece is they have equipped and how to obtain it. There are some pretty cool looking sets put together by players.

PvP Item Sets
This is a great place to see what is available for purchase using the AP points you earn. Very nice gear for PvP.
