To the right of the King's Gate bonfire are several stone soldiers and soul doors. Kill them before the doors to have the way opened, but beware--most chambers house a Ruin Sentinel. Open the last chamber on the left, and you'll be able to drop through the floor to a hidden area beneath the castle. Loot the corpse here for the armor set.

Havel's Armour (Full Set)
This takes an extra step to acquire. First, you need to retrieve the Forgotten Key from Black Gulch. To get it, look for a series of ledges you can drop down near the second large wall worm. Follow these to reach a large cave housing two giants. They're tough to beat, but doing so earns you the Forgotten Key.
Now head for the Upper Gutter bonfire in The Gutter. Make your way through the zone until you leap to this platform with the torch-carrying enemy. Climb the ladder here to find a door you can now open with your Forgotten Key. Inside is a crazy number of poison-spitting statues, plus a pot containing a corpse. Bust through and loot the corpse for Havel's Helm, Armour, Gauntlets, Leggings, and Greatshield.
