In today's weddings, we have filmed brides who wore kua in the morning with or without the red veil and only changed into her white gown for the banquet. There are also brides who doesn't have any veil for the white gown in the morning too.
A collection of photos of the bride with an interesting veil that she had on for the solemnisation:

Do check out the last photo in this other set:

Most importantly, we may wish to seek our elders opinion in having the kua / gown for the morning session. During solemnisation, the bride typically wears her white gown (in a church setting) or white dress (without the long train) at a smaller venue (eg. ROM at fort canning). Most church weddings, the bride will have a veil on. In smaller venues, there may or may not be a veil. It all depends on the look that you would have for the wedding too.
Hope this information helps.
Cheers,
