OK, both Yuki and Michelle noticed the change so either Kate went to a lot of extra work to give them each a risque illusion or she’s using the type of illusion that modifies light and can be seen by everyone. The later type should also be visible to a camera, so the pictures could be given to an expert dressmaker to make non-illusory bridesmaids’ dresses (probably not this variation, though). Now, who have we recently seen who works with clothing and understands how to support measurements like Michelle’s or even Yuki’s…

For the wedding night? Very appropriate. For the wedding itself? Not so much…
