This is his full mage outfit, the belt holds a few interesting items, starting from the two potion vials located at the front, they are HP and MP potions respectively, they are enchanted to refill once the contents are consumed, theoretically being an endless source of HP and MP recovery, though they still need to draw from an origin point, in order to refill, so when that original source runs dry, so to do the potions.

The pouch next to the vials is simply a money bag, also drawing its contents from an origin point.

The two bags on his waist contain various catalysts, like evolution stones, to other relics to augment or alter his magic abilities.

The belt itself is also enchanted to scale with the wearer, though its capabilities to do so are slow off the mark, as a drastic and sudden size increase can cause it to fit too tightly around his waist, or snap right off the same applies to the rest of his clothing.

His clothing uses a magically enhanced material that helps increase his MP he is capable of absorbing, and can store it within the fabric itself, rather than inside himself, however it is very limited in how much it can contain, and should it be damaged significantly, it’s stored MP will funnel into the wearer.
