Some have the custom of putting on a new tallit after the reading of the ketuba. Among other reasons for this is that while the Sheheheyanu blessing is not recited as part of the wedding ceremony itself, the wearing of a new tallit enables the groom to recite this blessing.

If the ceremony takes place before sunset, he recites a blessing before donning the tallit:

“Blessed are You, Lord our God, King of the universe, who sanctified us through His commandments, and commanded us to wrap ourselves with ritual fringes.”

If the ceremony is held after sunset, he does not recite the above blessing. In either event, the Sheheheyanu blessing is now recited:

“Blessed are You, Lord our God, King of the universe, who has given us life, sustained us, and brought us to this time.”

When reciting this blessing of joy and thanks over the tallit, he should have the wedding in mind as well.
