I have pretty straigh/wavy hair B”H but for dates I usually wave it towards the bottom for a pretty look (and leave the top and my side bangs straight).
As for the black clothes I love black! But if u would look in my closet u would see COLORS! white skirts, gray skirts, pink skirts, I wear all color all the time but I love black too. U just have to know how to dress and have a nice style 🙂
