What can I do to spice these outfits up?

Okay accesories are key here...look into getting some great necklaces...look for mettalics silvers gold tones and bronze are hot at the moment...layer necklaces and look into scarves for the fall....as for your sweater problem i would suggest a little short jacket....or a shawl...it sounds a little grandma ish but ttrust me a cute thick scarf which u d over you or bundle up in when u r chilly is very in.....good luck :D
