Selena Gomez Vs. Katie Cassidy Who Wore Big Shoulder Trend Better. Last week both ladies were spotted at the Hollywood Style Awards wearing one of the hottest trend for fall, the look of big shoulders. Both dresses were black for added class and while Selena's dress was chic and age appropriate, Katie's look had a deep v-neck for sexapeal. Both ladies look gorgeous wearing their dresses, and honestly I don't know who looks better. What do you think?
