In this photo here, I took and edited them myself. Using Lightroom and photoshop as the apps I used. The goal was to make it look like a catalogue so putting the white background was important in doing this. 

Once the photos were in photoshop we masked the sweater to get rid of the background. Then I put them together and ensured that they were aligned and changed the pixel size to make sure that they were all the same height. The width changed automatically but overall it came out better than expected for my first time.
