The invitation featured iconic Venetian imagery like gondolas and bridges, along with illustrations of birds and butterflies.

Jeff Bezos and Lauren Sanchez arrived at the ultra-luxurious Aman Venice hotel in the Italian lagoon city on Wednesday. The couple is expected to tie the knot later this week and are hosting a lavish celebration for their 200 closest friends and family members in Venice.
