This happened at a little store where everything went well until I asked about flattening the dress. I tried on quite a few dresses, some terrible, some cute, and all hilarious because of how much empty space was at the top. Finally, I asked if there was any way to fix that. The person helping me offered some padding. Now, these dresses were probably a D cup if not larger, so that would require a crazy amount of padding--and we tried, it was madness--and since it was low cut it just wouldn't look attractive. Not to mention, I don't have an issue being flat, so I don't see a need to pretend I'm that large. So, I decline, and ask instead for the dress to fit me. I offered to pay for it, however much it would be.
She just wouldn't hear it. It's my wedding day, and I should go out there and be all "girly"! I should have large breasts because only that way will I be feminine and beautiful! I'm clearly just confused. I shouldn't want to be flat chested. It's just not right!
Finally, she did agree to it, told me how much it would be, and we continued dress shopping. When it came to crunching numbers for the dress, though, the argument started again. She just wasn't comfortable with tailoring the dress when I could pad myself. She offers free padding and tells me of stores where I can find padded push up bras. When I decline that, not only is the padding free, but so is attaching the padding to the dress! This wasn't a money issue--I never even expressed concern over the price--so I am clueless as to why she was offering that free of charge. Why is it so hard to get I'm comfortable with my appearance?
Needless to say, I didn't buy a dress from there. I went elsewhere where they didn't question me, and my dress was not only flat and awesome, but it looked like me underneath.
