Here is a pic of the closet in question:

Do you think its possible that Allen used the word "clothes-press" as a colloquilism? All closets were clothes-presses to him?
From Bridget's Preliminary Testimony:
Q. Have you given me a description of all the clothing you were in the habit of keeping in that kitchen that goes to the north door, or rather in that entry way?
A. Yes Sir.
Q. Did you have a clothes closet in the kitchen?
A. No Sir.
I wonder if Lizzie would risk hiding a dress in that closet in Bridget's domain as it sounds like she is all over the kitchen. Its not stated where the closet is, but, Bridget mentions going to a closet upon coming up from the cellar to get a brush to wash the windows with. It may be that kitchen closet, sounds like Bridget keeps alot of stuff in there.
Bridget's Preliminary Testimony:
Q. What were you doing in that forty minutes?
A. I always put away the dining room dishes first, then I had a good deal to do to straighten my kitchen, and to put everything in the closet, and straighten my stove.
Also:
Q. Where did you keep the flat irons?
A. In a little closet, back of the stove in the kitchen.
Also:
Q. Now this small ironing board which you say they were in the habit of using was kept where?
A. In the kitchen closet, behind the door.
Also from Bridget's Preliminary Testimony:
Q. Did you have any books there?
A. Yes Sir.
Q. Were not there some old Harpers there, a magazine with pictures in it?
A. Yes Sir.
Q. Where were they kept?
A. In a closet in the kitchen.
From Alice Russell's Trial Testimony:
Mr. Moody. (Showing plan to jury) She says the stove is the place she has indicated by the mark, with the fire part of the stove towards the closet, that the closet door was open; that she was standing between the stove and the closet door, and the point indicated by that cross; That halfway up the shelves in this closet, the door of which was open, was the waist of this dress.
Q. What was that cupboard, as you call it, used for? What was its use?
Mr. Robinson I don't suppose that is of any consequence.
Mr. Moody I want to see if it is a clothes closet or a food closet.
Mr. Robinson It does not make any difference, I submit. It was simply on a shelf there in the closet.
Mason, C.J. She may answer one way or the other.
Mr. Robinson Very well.
Q. What do you say Miss Russell? Was it a food closet or a clothes closet?
A. As near as I remember, there was coal and wood kept in the closet, and on the other shelves I remember seeing flat irons; that is all I remember: there were kitchen utensils.
