Accessories will be your best friend even for a simple outfit! For necklaces, don't go for long ones Bc they will go in you boobs or to the sides and it will look awkward(sorry if I'm not classy, I'm a girl so I know) go for shorter necklaces so they look cuter!
Just wear what you feel comfortable and confidant in. If anyone says something about your outfit, just ignore it. (I know this may not be what kind of answer you want, but it's really the truth)
