Even if you feel that turtlenecks are unflattering, you should still own one for practical purposes. Even if you live in Southern California! What if you decide to go skiing?? You will be so cold in shorts and a tank top! So buy some pants, too. Those are very practical.
On a side note, if you're ever in Seattle, make sure to get yourself a cupcake or two at Trophy Cupcakes. I think they are the best. Their chocolate frosting is the pinnacle of perfection.
And that is my fashion tip for the day: Buy cupcakes and pants.
