I don’t wear particularly low cut tops or tight clothing but I’m naturally large breasted and it’s quite difficult to hide 
There’s a manager at work who constantly stirs at my boobs. Usually when I ask questions or need help with tasks I see his eyes wonder. At first I thought it was because he’s shy so he was looking down a lot but he doesn’t do this to anyone else! It’s getting to the point where it’s embarrassing now. Would you say something or just let it go?
