I always find the transitions between seasons to be the hardest, style-wise. In February, you still probably need a sweater, but (hopefully) the weather is warming up a bit. So I like to use a few pieces that work in both spring and winter. And a touch of pastel makes it feel like the long winter is finally coming to an end.
In this outfit, I just took a short-sleeved pastel sweater (though a full-length sleeve would work too) and paired it with a basic black skirt ankle booties and then added black and white accessories to add some pizzazz.
