Ah, a wee hole. Ingenious-maybe. I couldn't trust myself to pee straight enough not to soak them either lol ! I'd have to invest in a she-wee ( not happening !)
Remember Ross on Friends trying to get his leather trousers back up: "the lotion and powder have made a paste!"? ...and there's not much room to manoeuvre in a toilet cubicle! A tinkle facility in these pants is all well and good if that's all your need to do!
I once bought an all-in-one thingy to wear under a long dress and while it did give me a fab figure, I'd not given any thought to ... ahem, 'comfort breaks'. It had a 'wee hole' too, but no way was I trying that, so everytime I went to the loo the dress had to come off and I had to wriggle out of the all in one. Every time I went to the loo my OH wondered where I'd got to it was taking so flipping long!
I do seem to remember about a year ago they had some spanx / shapewear and they used ordinary women with flabby areas. The demos were brutally honest but showed the products were quite amazing with the results they achieved. It was a bit cringe-inducing to see the muffiny midriffs splurge into sight like flobbity blob of pastry dough once the magic spanx were removed!
