the badou r in minamiaoyama is THE location to go to if you see only one 45 rpm store. it's tucked away off the main streets in a japanese-style house, so you have to switch your street shoes for comfy slippers once you step into the front foyer. you feel like you're browsing through a friend's huge closet because of the comfy factor as well as the super friendly staff.

the other badou r in the area, badour r ai is on a main street with a more urban feel
and the third one, the smallest of the three was 45 ai indigo, or maybe it was an umii908 store. not really sure. but all these brands are under the same 45 rpm family.
and this is a scarf that showed up in every location. as if it were asking for me to take it home.
there are a couple us locations of 45 rpm if you're interested. both are in manhattan.
