4 Months before the wedding

Book your florist.  Once you have found one that appeals to you be sure to secure your order with a signed contract and a security deposit.  Be 100% sure of your selection, and know the refund/cancellation policies in the event you cancel or change your date.

Shop for your wedding bands.  You should do this with your fiancé.  You will both be wearing these rings for a long time, so you should both be happy with your selection.

Visit your physician. Get your physical examinations and blood tests if required to obtain a marriage license in your state.
