what is the correct outfit to wear the shiny outfit from the park? the boots and the bra wear just fine but the one piece
I dont understand your question. If you want to know how to find all the Silver Slut items, after finding the first one, in your journal it should start telling you where to find the next. If youre asking how to find the clothing in the park, you need to choose the option "Go for a walk" instead of explore.
If youre asking how many items there are regarding the Silver Slut, I believe its 5. Boots, Panties, Bra, Leotard, and finally the Collar. Upon wearing all 5 items at the same time, you will unlock the Silver Slut storyline. You will also lose most of the silver slut items, to become the silver slut, you simple need to wear the collar as part of any outfit, events play out in the city, you will know as you will see in red text "your collar is vibrating".
If you didnt mean either of those, then you need to try asking your question again more clearly.
