iPhone - Quick usability test with a paper prototype

The users:  

5 users, 4 women, 1 man, between 26 and 40 years old, 4 iPhone users and 1 Android user.

The results:

Home screen - no problem

Costume doll:
Wrong expectation - One user expected that the element "..." means the doll in same outfit with another colour.
Wish - One user wished not only skinny models but also normal models. The user suggested having a possibility for choosing the size of the model.

Wardrobe:
Wrong expectation - Wrong expectation for the label of the navigation buttons. "Add" is preallocated by the meaning "Add to shopping basket". "Buy" created the expectation with two users to go directly to cash. Suggestion from these two users: Change the label in "Dress" and "Add" or use icons such as shopping basket and plus button with t-shirt icon.
Wrong expectation -  One user expected that the clothes rail works like a cover flow.
Wish-  Sub category for example for blouse, t-shirts and pullover. Double clothes rail.

All users preferred the alternative with the t-shirt scrolling through the wardrobe.
