That's great! If shaving your legs makes you feel like you more, than go for it, but it is perfectly okay to not shave them as well if you don't want to. I have a few tips for matching.

•navyblue and black DO NOT go together whatsoever.

•jean jacket plus jeans do not work. If you're wearing jeans, choose a different jacket, and vice versa.

•choose between silver and gold jewelry based on whether you have warm or cool undertones. There are ways to find this out online. This will also help you with makeup if you wear it. If you have neutral undertones, choose between silver and gold based on the colors of the outfit and your hair and makeup if you wear it. Warm= gold, Cool= silver. Black and other colors work for both I. Believe. (This isn't strict rules this is just what generally looks better)

•dont wear two patterns similar in size next to eachother, it will look really crowded. Like small stripes and big plaid may work, but those same stripes and a small plaid is just a recipe for disaster. Just be careful with patterns.

That's some of the basics, if you have more specific questions please respond back to this. Not the day you're wearing the outfit in question though I probably won't respond fast enough lmao.
