When dressing for a casual party you want to be well dresses, but not over dressed.
Here are some tips:
Elevate your everyday look. You can still wear jeans if you want, but pair them with a fancier top. I love this track pant option because you will be comfortable and casual without wearing jeans.
Choose easy, fun accents. You don't have to choose between being comfortable or being stylish. This stacked heel is much easier then your normal stiletto. Also, this statement necklace is that perfect fun accent, everyone will comment on.
Add an effortlessly cool twist. Try a little styling trick like pushing up the sleeves or rolling your pants. In this case I picked a over sized sweater for that effortless look.
