Okay so I have a 16th birthday house party this weekend and Im not sure what to do with myself. I know what dress Im wearing; a plain black dress that kind comes out as a skirt on the bottom half and comes to just above the knees but im not sure whether to wear it with or without black tights? also I have longish hair ( just below my shoulders) and im not sure what to do with it, straighten or curls? any makeup tips or ideas for shoues would be greatly appreciated too as I have no idea what to do with that either!
