There are several male costume options that can go with a witch costume. Some ideas include:

• Warlock: A warlock costume can include a top hat with a skull on it, a skull-topped walking stick, a suit with a black or dark red shirt, pale makeup on the face, darkened eye sockets, and a pentacle necklace or ash pentacle on the forehead.

• Wizard: A wizard costume can include a robe, a beard, a pointy hat, and a staff or wand.

• Devil: A devil costume can be a good match for a witch costume.

• Voodoo man or witch doctor: A voodoo man or witch doctor costume can also be a good match for a witch costume.

• Male witch: Male witches are not commonly referred to as warlocks, but a warlock costume can still be a good match for a witch costume. A warlock costume can include a hooded cloak and dark clothing.

These are just a few ideas, and there are many other options available. It all depends on the specific witch costume and personal preference.
