To dress as you want to Praise the Sun, you will have to have reached the Sands Between. In this place, you can find a small, oceanic version of a Dark Souls fire. It's located on the eastern edge of the Sands Between, behind a purple block of Umami that you need the Mantis Punch Adaptation to get through.
Go south from the Secluded Ridge Moon Snail Shell in this area, and look for some rocks near the ledge. It will be close to the tire. In this circle of stones is a bonfire made from a battery-operated candle and a set of sword-shaped toothpicks.
