Ordered tuxes today but........

they told me that fi should get a white shirt even though my dress is ivory? i brought pictures of my dress and the bridal party dress and color and she said that even though it is ivory it's a very pale shade so the traditional ivory men's shirt wouldn't go. she said that shirt was more in the butter cream family.

i tend to agree with her based on the shirt they were showing us.

did anyone else have this issue and what was the outcome?
