Dani, you have a great bod for clothes but what you're wearing just doesn't seem to fit. The pants look huge. They might feel like they fit but they are really very baggy along your leg and the color is a bit dull. I think you would look great in some dark wash jeans that fit closer to the thigh, either bootcut or straight. The sweater is also very shapeless the way you're wearing it, but could be salvaged by a great belt. Look at these entries to see what I mean:

I think you need to scrap the pants and try wearing the sweater in different ways. From what I see a belt is definitely a worthwhile accessory for you. I also think instead of wearing 3 dainty little pieces of jewelry like you're doing now, it's a lot more fun to wear one great bold piece of jewelry that really makes a statement and doesn't look so timid. Hope that helps!
