lose the bracelets and opt for something more plain, maybe like a navy undertop and some colourfoul shoes, or with like a 50's swing skirt and some dark tights and bright shoes.
i agree with annaharty regarding the blazer. if i remember correctly you do have a black blazer from the previous posts, it would look great with this outfit. don't really like the idea of a necklace as it would clash with the top's design
