How to buy from a wedding registry
Find out where the couple is registered.
You may need to ask the bride's or groom's parents or a member of the wedding party. Some couples include this information in the wedding invitation, but it is generally considered impolite to do so.

OPTIONS:
(A). If the couple has a wedding website, they may include the registry information on the site. Typically, a couple will register at more than 1 store.
(B). The bride and groom both must have married in the last 16 months and get their certificate of marriage (issued by their state or country). The destination marriage registry is more transparent when it comes to the area where both guests live.
(C). Consider what your potential guests will wear. You may want them to wear prints.
(D). Whatever the case, you should then make sure that you understand exactly what is the procedure in terms of registration. Confirm the ring order information for marriage certificates.
