Not only do you have to choose attire for the bride and groom, but also for the bridesmaids, flower girls, ring-bearers, best man, maid of honour and groomsmen. You have to find a site whether you're having an outdoors wedding or an indoors one. Then there's the flowers. The videographer and photographer bring up more questions. Vendors of every type and form are the most common option available to an engaged couple.
Word of mouth can come from many different sources and in many forms.
Whether you choose to ask a friend, family member or a different vendor, this is the preferred method. It allows the couple to find out what the general opinion of the vendor is, as well as what that person's experiences with the vendor was like. The couple can discuss the general attitude of the vendor as well as the amount of professionalism that the vendor exudes. One person's opinions may or may not mesh with those of the couple. It also tends to cause the couple to follow their instincts less closely.
