I am helplessly laughing here....
Not a true IT but I have in fact been stuck in a top in a dressing room. Also - worse yet -- on one memorable occasion, in a sports bra.
Could. Not. Budge. It.
This is what I get for being really small busted. I looked at the offerings. I looked at my chest. I picked up the smallest bra they had. It made sense, at least from the front view. But the small styles are all pullover style, with no clasps....
I didn't know whether to feel more frustrated or relieved by the fact that this was The Bay, so there was no sales assistant within miles of the dressing room. I did start to panic after about 20 minutes of fruitless wrangling (getting sweatier by the minute...). Finally by some miracle I managed to wrest the thing off of me and get out of there.
