Hello, I just got the Deep Bamboo hat from Patrigio's Secret Shop Event quest. I'm trying to complete the "Slovenly Ronin" look and I saw this reddit post of a guy's character wearing this Purple (brown?) robe with 1 purple and 1 green bottle attached on the waist.. Where Can I find this robe? Does any veteran player know what this robe is called? 

I know this is probably a male only robe because the Deep Bamboo hat is Exclusive: Warrior, Hashashin, Sage, Berserker, Striker, Musa, Ninja, Wizard, Archer

If anyone know what this robe is called please let me know. thank you

I just found out it's the Rebar set for Wizard Class, but unfortunally I can't get the robe look on Ninja Class since Rebar set look according to each class. I wish there's a way to wear different class outfit );
