So when you are getting noticeably bigger by the day, it might seem like you will never find the perfect fit.
But a very modern solution has now arrived with the launch of a new bridal shop specifically aimed at pregnant women.
Expectant Bride offers personal consultations with women by expert designers who are able to predict how big a bump will be on the customer's special day, and design the dresses accordingly.
The shop was set up by Tracey Wilkinson, 31, after she experienced difficulty finding a maternity bridal dress to fit her when she married.
