Failed Mcr Inspired Dress

I started out this project feeling uber excited to finish.... feeling that it would come out great and I could wear it to school the next Monday. WOMP :/ I took two black tshirts to make the dress portion. I resized the sleeves and made them puffy (it came out quite perfefctly, might I add :/) and added the pink bias tape detailing. Sadly, the bias tape makes the entire dress bunch up so I can't wear it. It looks horrible :[
When I showed my mom she gave me a "not all fashion designers get it on the first try, honey" Hahaha.
Maybe I'll try again and make it work next time :]
