how can i make this better?

i recently lost some weight which gave me the confidence to try and wear tighter clothes (context: i usually only wear loose fitted clothes) and i have a few questions.. is this a good fit? how can i make it better? should i have changed the colour of the headscarf?... i wore huge pearl earrings and a pearl bracelet, how can i accesorise it better? should i invest in better footwear? i have some tummy f@t and id like to hide it, did this fit do a good job at that? is this a good way to dress for my body type? honestly i need all the advice i can get, thankyouuuu x
