My baby daughter (youngest of four) was married in March. Her dress was this size. Different style, of course.
Interesting factoid -- in the current fashion of strapless gowns, my daughter had to search all over the country to find a dress in her tiny size that did NOT have bare shoulders. Eventually she found one and we bought it over the phone.
Later, she discovered that Prince William's Kate had wrenched the wedding dress fashion industry back toward sleeved, shoulder-covered styles. And why did she go that route?
Westminster Abbey will not permit brides to wear sleeveless, strapless gowns during wedding ceremonies. Old fashioned notions of modesty and all that, dontcha know.
It may be the case that in older European churches and cathedrals strapless/sleeveless just aren’t allowed. A friend was married in France a week or so ago and I noticed the bride wore what appears to be a shawl in the church that wasn’t there thru most of the reception.
