This is one of Jill's alternate costumes in the Boutique.
She wears a short sleeved pale blue shirt with the sleeves rolled up slightly.
There is a logo on the right sleeve, but it's really hard to see if it's the S.T.A.R.S. or RPD logo.
There also seems to be a gold pin/badge on the left side of her chest.
Jill wears a darker blue pencil skirt, very short, and a black belt with gold buckles.
On the back right of her belt is a set of silver handcuffs,
and on the left is a black police baton/truncheon.
She has blue shoes with a small heel which match the colour of her skirt.
She wears a police cap of matching blue with either the S.T.A.R.S. or RPD logo on the front.
