What to wear when it’s not quite sweater weather, not quite right for short sleeves? In those in-between days when the season is sorting itself out, dressing at Harvard can be a head-scratching task — especially for those incoming students hailing from balmier climates. For some, the schizophrenic months of autumn are the perfect opportunity to pair a short-sleeved dress with sheer tights; for others, it’s a time for layering a light cardigan or jacket over an ensemble, something that can easily be whisked off on a hurried walk to Widener. Navigating through Harvard’s Common Spaces — the Yard, the Porch, the Plaza — an assortment of intermediate looks is everywhere. And as the days grow shorter, one thing is clear: Show some skin while you still can.
