Happy to help, please just call me Mandie.
I just found two funny stories what happens to those lovely and richly made gowns. It from the book "The Court of the last Tsar; Pomp, power and pageantry in the regin of Nicholas II" by one of our members- Mr. Grey King.
"Once, Grand Duke Michael Nikolaievich caught the train of Grand Duchess Vladimir (Maria Pavlovna)'s gown with his spur, which she unknowingly dragged behind her, Her Page ran forward, atempting to grab the yards of lace and velvet, but succeded only in shredding even more of the fabric as the grand duchess struggled on."
"Then at another ball, once, Grand Duke Michael Alexandrovich was waltzing with Nadine Wonlar-Larsky when he caught his spur in the hem of her gown. He tried to disentangle his foot, but as he did so, he ripped the bottom of the dress away, dragging rows of lace and satin with him. His startled partner tried to balance herself against this tug of war, but both ended up in a heap on the floor, watched by thousands of mirthful eyes."
Lol!!
