Tell them you took it and your underwear off for a mundane reason

You decide to play embarrassed and lie. You move your hands up to cover your boobs over your shirt as you say, "Eeek, that's embarrassing! I didn't know I was showing so much! I took it off in the bathroom because it was really itchy. I think we are using a new detergent, because some other clothes were itchy too."

The guys slump a bit as they think the shows over, one of them asks, "What do you mean by 'other clothes?'"

You respond, "Ummmm, well I kind of took my underwear off in the bathroom too, I couldn't take the itchiness any more."

The guys get wide-eyed again at your revelation, but they choose not to mention it. Instead they ask, "Well at least the rest of your clothes aren't itching, right?"

You consider how to approach this for a moment. After some hesitation, you decide to play this game.

"Well to be honest, yes they are. Like super itchy." You quickly drop one hand to scratch your leg, revealing your breast for a moment before covering it back up. You have a charade to uphold after all. They all perk up at the glimpse of your boob again and perhaps get an idea about your situation.

One of them says, "Well that's no fun, you should get out of those itchy clothes!" The others mumble in agreement.

You pretend to be sarcastic in your own adorable way as you say, "Well it's not like I can take them off here!" You give an embarrassed giggle at your slightly inappropriate joke.

As if sensing a shift in the mood, the men look at one another and then one speaks up and says, "Well I mean you could, it's practically your restaurant after all!" They all laugh, hoping you don't get upset at their risqué response.

Do you tell them that's not going to happen. It might happen, but you don't want them to think it was their idea. Do you tell them there's spare clothes in the back and then walk away. Going to the back gives you time to think. Do you tell them there's spare clothes in the back and ask them to help you find them? You already know where they are, but you want them to come along for some fun. Do you tell them they're right and keep the risky talk going. You like the idea of them imagining and talking you into your exposure. Do you tell them they're right and act apprehensive. You know you want to strip, but you don't want them to know that. Do you tell them they're right and start to undress. Their reasoning is bad, but it gives you an excuse to strip.
