Arrange some quiet time for just you and your fiance during the wedding planning process. A romantic date or a weekend away will give you a break from the stress.
Bridesmaids dresses do not have to all be the same design. However, it is best to keep them in the same color family or style.
If you are having an all white wedding, try to incorporate a small pop of color somewhere, such as in little wedding favors, to create drama.
