In my briefcase or in a jacket pocket. Really want a holster but haven’t had the time to investigate or the money to spend.
Pretty much my right pocket or right jacket.
I get to much attention with a
Holster, it also hits your leg when you walk.
Mostly my left pocket since I’m left hand but I does end up in my right most times as well.
I have 2 front pockets on my work uniform shirt, good for 2 yoyos. 
Front Right
I usualy put it in whichever pocket is free, and if both are, right pocket=right handed.
I wear dickies w the utility pocket and it fits a yoyo perfect
I sometimes wear two holster the one with the loopers is on my left (in my pocket as well as on my holster) and my DM2 on my right (not in my pocket)
Coat or sweatshirt pocket.
Use my Crucial holster or just brig my throw bag 
left handed in my left pocket. skinny jeans do look awkward with it though lol
Left, my right has a hole in it.
I usually rock two throws per pocket, one full full metal per pocket, so I usually have my PHENOMizm, Roll Model, Gnarwhal and one of my Adegles on me, the PHENOMizm is not metal on the outside so it can be in a pocket with a full metal.
