Well, I know this isn't "Can you top this?" but I think you'll get a kick out of the story I have:
When I got married I was in my late thirties, and thought I would look ridiculous in a traditional wedding gown. I lived in New York at the time, and was a corps dancer for NY City Ballet, thus very used to dressing in strange and uncomfortable costumes. I didn't want to wear another costume. I wanted something that would be more age appropriate than the "here comes the bride" dress. Like maybe a mother of the bride type suit with a jacket (the wedding was in mid January.) I asked my closest friend, who was an instructor at one of the colleges, to be my maid of honor. She was in her early thirties, and wasn't dating anyone at the time.
We went to a bridal salon, and I headed over to the "mother" dresses. And my friend decided she wanted to try on a full-regalia wedding gown. She did.
After the try-on appointment, she went back and purchased it. Plus, I was pretty shocked to find out that this wasn't her first purchase of a wedding gown: Another one already hung in her closet!
With the prices of such dresses, yeah, I do think it's a little weird to buy one without a wedding date or even a potential groom in the picture. Additionally, your friend is going into a shop and trying on dresses with the assistance of a fitter: It isn't like going to a dress shop or a department store and independently trying on clothes. These fitter/salespeople get paid partially on a commission basis. I don't think it's very fair to be using their time without intending to purchase something.
Speaking of crazy things that women like to try on, I had a regular pointe shoe fitter at the Freed store in Long Island City. One of my bunions was getting worse, and I went to get re-fitted for shoes. Because I was a professional, I used to buy them in large quantities and got a discount (plus a shoe allowance from my company.)
On this one particular occasion, I was once again trying on a pair of pointe shoes and in walked a young woman in her twenties along with her mother. She wasn't a dancer, or even a ballet student. She was a bride-to-be, and told the saleswoman that she wanted a pair of pointe shoes for her wedding ensemble. The saleswoman looked mildly horrified.
A couple of other dancers were getting fitted, and we decided to watch the fun. These shoes aren't made for walking, or doing much of anything other than classical ballet. They're uncomfortable enough for dancers, and ten times worse for those who don't know what they are and how they're used. One of my students told me that the first time she put on pointe shoes, she didn't feel like a ballerina: She felt like an arthritic drunk. They're not durable, either. They last a professional one performance (maybe) before they lose their support and start to fall apart (students get more mileage out of them, maybe a month worth of classes three times a week.) They would not withstand the rigors of a church ceremony, picture taking outside on the ground, and then a wedding reception. The saleswoman tried to explain this. So did the three of us, and even showed her our blistered and callused, ballet-scarred feet to try to dissuade her. But no, bride to be wanted them. And Mamma chimed in, too. The saleswoman sighed, indicated to the young girl to have a seat and take her shoes off, measured her feet, and went and got a few pairs. She put a pair of them on bride to be's feet. The look of shock and pain on the girl's face was priceless. Then the saleswoman told her to stand up and walk a few feet in them. The poor girl hobbled about ten feet, turned, went back to her chair very gingerly, took them off, and she and Mamma nearly ran out of the store, hopefully in pursuit of something more suitable for her needs and her feet. That would have been anything!
And we three dancers nearly collapsed in laughter!
My old friend never did marry by the time I left NY back in '06. We've lost contact since I retired, and I never knew what became of her two very expensive wedding gowns. I hope if she sold them, she didn't lose too much money in the process.
