My soccer team went to a fancy restaurant for team bonding, and I didn't have any nice clothes but I didn't want to say no (plus it wasn't optional), so I showed up in a hoodie and jeans even though I knew I was probably underdressed. One by one they all walked in, wearing sweaters, dresses, skirts etc with makeup. Some of them poked fun at me for thinking it was a "casual" restaurant. Then the coach gave individual awards and some team apparel out at the end, and he called people up one by one. I had to get up in front of EVERYONE and they saw that I had no nice clothes. They were really quiet and didn't clap that much for me. I'm still ashamed thinking about it.
