Looking into getting a RL Big Pink Pony Polo. They are the skinny fit, and I keep reading to order a size up. Agree? Disagree? If I wear a large, do I go up to the xl??? Do they shrink? I think I'd be happier if it was too big than too small, but I just want to get some opinions! My hips are wider than I'd like them to be and that always makes things fit worse. I'm also looking at getting the Big Pink Pony Zip Up Hoodie. Could I order that normal sized? Thanks ya'll!
