well
you have to give to arceli cold water
you can do that by taking the ice tray from the freezer, put water on it in the sink, and then freez it in the freezer
the pick up glass, fill with water an put the ice that you made on that cup (you have to remove the glass from the inventory slot to put ice on it)
when you give it to her she's gonna go the bathroom, in that moment you can collect the cutter that she leaves on the sink next to the bathroom
go to her room and in one of the drawers there's a pattern that you can use on the black sheet she was working on
collect the new made suit and there you have it
with that you can go have a nice time with shontel
(didn't know if anyone already put a walktrought but f it)
