Before using actual fabrics that I got for this project, I made the prototype of it out of tracing paper.

Here is my shirt (the front view, the side view, and the back view):

I also tried to put it on, and it fits perfectly, later on my actual shirt I will also sew the buttons on.

My theme for the project is related to the theme of flight, airplanes, and wings, so therefore I decided to make the sleeves in a shape of a wing by folding it:

My container will be in the shape of an airplane, so basically while making the prototype of it on a tracing paper, I found out that I will actually have to fold it exactly the same way as usually I make small paper airplanes. I will use 3 zippers on its sides, and will leave two packets on both of its wings.

I also experimented with putting my two objects together. Unfortunately, it is not that easy to try all different ways of fitting in the shirt into the clutch because tracing paper is not that flexible and is very easy to tear apart. Apparently my two paper versions of the final projects are related to each other in size:

On the bottom of my clutch I will hide a thin plastic line in order to fix the bottom of the airplane, plus it will give my clutch more inner space to fit in the entire shirt. Here is the sketch of it:
