Shirtless app flow

hello guys!
I would like to show you my ideas for the e-commerce clothes app. I focus on cute but simple design, following all must-haves in e-commerce apps, from simply intuitive UX to friendly UI.
I was trying to show all the most important pages: Landingpage, Main page, Campaign page, Product page, Add to cart function, Cart, and Thank you page, with those basic screens we are able to start our business!
Hope you'll like it!
