Is this sexual harassment?

an

On Friday, my coworkers and I were offered tickets to see a baseball game together. I went with three of them. Everyone was pretty drunk. But then an older man who is a director (I'm an entry level worker age 23) at my company kept talking about my breasts and making jokes about them and how he's thought about them. I was so uncomfortable but too tipsy to know how to make it stop. This is sexual harassment right? And we have a horrible HR team that I don't think will help me solve this.
