Hello! I am currently a BME student (junior) at KSU and got invited to an ECE banquet to both socialize and present for a couple organizations I am a part of. The problem is, the invitation states no dress code and I only know men who are going/have gone. I have genuinely no idea what to where. I do not currently have formal dresses but am willing to go buy some if needed. I do own some business casual, but I feel like some of my tops may be a bit tight for what seems like a formal event. Any input is greatly appreciated. Thank you all
