How can I improve my online fashion store's design and appeal?

Hello, again, so i spend some ads on pinterest for conversions(which means it drives people to ur website for actions like place an order etc…), and i wanna make sure my customers have a smooth great experience making a purchase on my store, so can u please go back on my store and tell me what suggestions i can do for my customers to have a great experience?

by the way, i decided to do lifetime budget at $14 from 12/18/2023 to this saturday 12/23/2023; based on what i sell, i put interests like women’s fashion and wedding and more like handbags, coats, beanies, summer dresses. ; i put all genders, all US locations, all ages and the potential ad users was 80million +. so based everything i did, did i do good for creating this campaign? please provide honest advice.
