Working with special colors

[Alexajlex]

I have some pics I took of a couple and the bride to be was wearing a very nice dress. It was white shinny and with a bit of pink in it.
The florescence was making accurate color correction an issue due to the whiteners added to the fabric.

How do you best deal with this?

I tried several approaches.
The straight forward (WB fix) makes the dress white, shinny not white-pinkish shinny.

The other way would be by boosting up the colors and using a mask so the whole pic does not have a red color cast (a bit time consuming).

I'm open to suggestions on how to best approach this.

What kind of white balance adjustment did you make?

What kind of white balance adjustment did you make?

I did the WB tool in ACR on the RAW file and sampled a white shirt in the pic
and I also did the digital "gray card" (Chip Springer's digital gray card).

These both worked OK but due to the fact that this particular color was very faint+the whiteners in the fabric (I suspect) this would turn the dress almost totally white.
