Cis woman here. Based on your dimensions, you're going to struggle with the sad phenomenon that is vanity sizing: get ready to try on a lot of poorly-fitting clothing and walk out of a lot of stores empty-handed or with clothes that are just meh. I don't know where in the world you are, but if you're in the US my recommendation is to start with stores that cater to the teenage and 20-something crowd. Unfortunately most "women's" stores and departments sell clothes tailored for overweight/obese women, and may be baggy and ill-fitting on you. However most fast fashion places (eg Forever 21) will probably have clothes that fit, and some of the trendy mid-scale places like Express should work too. You might also find success in the teen-oriented sections of department stores (Kohls, Macy's). You are definitely not petite, so don't bother there. Trends have also veered away from form-fitting, especially winter clothes, so you may struggle to find exactly what you're looking for, at least at first.
Oh, and if you want to jump on the long-socks trend, sockdreams.com is my recommendation.
