The top part is a regular shirt, the bottom part is actually made as underpants, because it has to go into the boots. The red "shorts" (?) with the yellow belt are painted on the underpants. The boots are actually socks, but because of the reflections, they really look like boots rather than socks. The cloak is a flexi prim attachment that should be worn on the chest. It might need some adjustments to your avatar.
This set is only available in my in-world store, not in the SL Market.
