Yesterday was my first day of work for a business at an airport and despite doing a great job in training, I got pulled aside by my female supervisor and was told she could see my nipples through my thin uniform polo shirt that THEY gave me. Didn't even know what to say. I wear multi layers, had my buttons buttoned, everything covered, etc and had no clue what to say. I refuse to purchase thicker or more bras just to please them, it's f'king HOT in the building/stockroom I work in. I can see I'll be finding another job eventually which is sad, because I liked this one.
