Similar dress to Sonia Replica Dragon B, but white?

So I fell in love with the design of the Sonia Replica Dragon B, but I'm not a fan of the gold. Does anyone know of a similar style dress that is white?

There actually was a white version of it on the JPN server, but several of the color variants for the costumes in the Shining scratch (and in several other scratches) were not included, likely to reduce the already large line-up.

As to a similar dress, I would say the Bridal Outfit, but it was part of the Fresh Finds Shop Recommended Items from 5/26 to 6/9, so it is not available to obtain at this time. Another possibility is maybe the Juno Charis, but it is a bit of a stretch.
