How to deal with a fullness of information?

When someone tries to orientate, the person will use knowledge from a similar environment (see Strapelkamp, 2007, p.151).

Based on this statement in the area of information architecture designers use metaphors of the real live such as:

The first example is "Magic Cap". It is an operating system for a Windows mobile. This example not only uses a desktop metaphor, it also uses a room metaphor (Strapelkamp, 2007, p.133):

The next example is an internet portal for the course communication design at the Fachhochschule für Technik und Wirtschaft in Berlin (Born, in Strapelkamp, 2007, p.144). The internet portal is designed like a virtual university with pool rooms, corridors and stairs:

This example is also related to rooms. It is a digital reconstruction of the flat from Ludwig van Beethoven in Vienna (Frings, 2004, in Strapelkamp, 2007, p.150) . A user can navigate with the floor plan: 

The last example is a map from the London Underground (Strapelkamp, 2007, p.147). This abstract map is also related to the real world. The map shows distances between stations in proportional relation: 

There are two types of orientation: The content-related orientation and the function-related orientation. The next picture shows a desktop metaphor for an operating system. This metaphor is a combination of both types, because the elements are related to a familiar environment:

Another way of classify these kinds of information is shown in the next picture. It is a tree structure of an office and it is an example of a content-related orientation:

Studies show that elements in a two dimensional room are more comprehensible. Because of this, the information structure related to the real live, like the desktop metaphor, should be preferred (Strapelkamp, 2007, p.133).

 Orientation in my application: 

According to the orientation theory from Strapelkamp (2007, p.130-151) it is necessary to evaluate the design of orientation for the device you working for. In my case it is the iPhone and the iPad.

The HCI guidelines from Apple recommend to design an hierarchical orientation structure (See post: iPhone - Interaction Design Pattern). Strapelkamp (2007, p.130-151) explains that a good orientation is based on tidiness and tidiness means to filter especially when there a lots of data, information and items. For example, related to the idea for the paper costume doll it means to give the possibility to filter the type of clothes.  Maybe it is also feasible to make a preselection with a criteria such as "What is trendy?". Furthermore, according to the theory that orientation is easier when information is related to a real environment (see above), I would like to integrate a clothes rail metaphor. The next picture will describe my idea in a small sketch:
