Ok - my most embarrassing ever slip story - and only 2-3 years ago. The company I worked for at the time had just been acquired (sigh!) by another software company. The new co was having their annual sales kick off meeting in a conference center on the Hudson River just north of the city.
Since I didn't know the usual drill, I decided I had better show up in a skirt as the co prez was pretty traditional. So I put on this long black skirt and hose. BIG problem - static cling! I never use hairspray, so I figure, what the heck, I'll just wear a slip. Of course, it has been YEARS since I wore one (and I only ever wore half slips as I am totally disproportionate in height above bs below the waist.
So I am standing at the front desk and I feel a funny feeling. I look down to see my slip pooled at my heels.

Fortunately no one else is in the lobby other than the check in staff and they are behind a counter. I am so smooth - pure adrenaline. I loop the slip over one toe. Step out with the other foot. Lift the slip to a waiting hand and et viola - slip it into my briefcase. Did not get any grief from my teammates ...

That slip never made the trip home. The rest went to goodwill when we moved to TV!
