It would all depend who's wedding it was.  For someone very close and struggling financially then I would happily pay and share their day with them

For an acquaintance then probably not

In this day and age it's understandable that everyone is struggling financially, if it's the only way they can have a memorable day then that's their choice.

I paid for my daughter's bridesmaid dresses as they were made locally, the bride paid for the fabric and bought the shoes, flowers etc.
