Overall, it was really good and I chose this site because image of the gown and hood changed as I made custom choices. Gradshop was cheaper, but didn't have the custom made viewer. I felt more confident purchasing a custom gown from youo because I could visually see the gown change as I made color and design choices.
I suggest that you store images of emblems from popular schools in your system so you can just select the right one without customers trying to search for a hi-resolution and transparent pic of the emblem from the school in a .jpg. It wasn't easy to find, so I didn't add the customization.
