Uniforms - HELP!!!

We have waitstaff that wander around serving drinks, food, etc. The uniform has just changed for the women to a boustier type top and a skort - the top is pretty revealing on big chested women. (Don't know if this makes any difference, but the guys are in black pants, white long sleeve shirts, red ties and a black vest.) There is no maternity option. Problem One: We have one waitress six weeks along who already says the uniform is too tight. The GM and department head want to accommodate her. Problem Two: The department had recently hired a woman on graveyard shift who is big. When she was hired, she was in the old uniform. When she went to get measured for the new uniform, it was found that it does not even come in her size. The GM does not want to accommodate her, and wants her moved to a different area. I think we have a problem here. What say you?

In your situation, I would accommodate both. Why not let them wear a white shirt, vest, and bowtie like the men?
As livin said this one is ripe for the picking and I would not want to make a shoestring decision on this one. I would bank that one day you are going to be part of a deposition explaining why you did what you did.
Frankly, the ladies will likely still choose the more revealing uniform with the hopes of larger tips. The ladies that choose to wear the pants will still look presentable (much more so than squeezing into a too-tight garment) and all will meet your dress code requirements.
good luck!
As a customer at a casino, I would not notice that not all of the females are wearing the same uniform. Nor do I care. Don't get hung up on the uniform thing, remember the reason the job exists in the first place, to service the public.
The image of a large woman in a boustier type top is gross. How would that poor woman feel?
