sure which florist to call, ask friends and relatives if they have recommendations or ask in a wedding planning forum. When you call, confirm that they can serve the locations for your wedding and reception. Most florists are happy to schedule free consultations to help you.
Take One Step at a Time
   The next step is usually selecting the gowns for the bridal party, because the flowers should compliment their color and style. Obtain some pictures or fabric swatches to show to your florist. In addition, before meeting with your florist, to go through a few bridal magazines and clip any photos of flowers and bouquets you particularly like. These simple tools will help you communicate with your florist, so he or she knows where to start in helping you select something you'll love. Even if you don’t know the names of particular flowers, your florist will guide you through the process
Meet with Your Florist
If possible, you should have the dresses picked out so you can bring your photos or fabric swatches with you and meet with your florist about three to six months prior to the big day. Earlier is worth it! Be prepared. Flip through bridal magazines, surf the Internet, and peruse books for flowers and different arrangements that appeal to you. Gather as many images as you can, and take them along when you first visit the florist. Your florist will be happy to select specific flowers, colors, and design styles with you. When you meet with your florist, let her know what kind of flowers you like, as well as those you don't like. After you and your florist have made all of the necessary selections, look over the proposal carefully before signing, just to make sure that you are both on the same wavelength.
Discuss Your Budget
Wedding flowers can be anywhere from a few hundred dollars for an intimate nuptial to tens of thousands of dollars for an impressive ceremony and reception, with the average normally in the $2,000 to $3,000 range. A lot depends on the location, number of guests, and how you want your wedding to be remembered. Be upfront with your florist about your wishes and your approximate budget. Your florist may be able to suggest ways to use some pieces at both the ceremony and reception. Many florists can also provide plants, votive candles, candelabra, linens, and other decorations on a rental basis to help you save money. 
Use Your Imagination
No matter what you see in magazines or at other ceremonies, remember that almost anything goes when it comes to wedding flowers. For example, compact nosegay style bouquets are popular, but so are clusters of calla lilies or other single flower types, and traditional cascade style bouquets are back in vogue, too. When it comes to color, pale pinks, peaches, and whites are always popular, but many brides today are opting for reds or more fashion-forward colors such as oranges and greens. The important thing is to work with your florist. He or she knows what's hot and what's not and can create almost anything your heart desires. So, whether your wedding will be simple or elegant, traditional or high-style, your wedding flowers will be perfect for the occasion.
Generally, the wedding style and formality you choose will influence the style of bouquet that you select. For example, if you are planning an ultra formal wedding, it's likely that your wedding gown will have a royal or cathedral length train and you'll wear a long veil. Your bouquets and other floral arrangements should also reflect this formal style. In contrast, for an informal wedding where you'll be wearing a suit or a simple dress with a sweep train or perhaps no train at all, you'll likely select a smaller bouquet, nosegay, or single-bloom style. A good rule of thumb is that your train length and wedding formality should determine the formality of your bouquet. Bouquets should always be proportional in size to the person carrying it.
Here are a few of the most popular styles to design your bouquet:
Round Bouquet
Simple, elegant, traditional bouquet that is suitable for both formal and informal weddings. Sometimes called a "colonial bouquet," this type of bouquet does not have to be perfectly round in shape and can be designed as a tight cluster for a denser look or loosely arranged for an "airy" feel. The flowers chosen for a round bouquet can influence the bouquet's formality.
Hand Tied Bouquet
Generally round in shape, this type of bouquet consists of a simple gathering of flowers, which is bound and tied with ribbon with stems left exposed.
Cascade Bouquet
This sophisticated and elongated style features fullness and an abundance of blossoms at the top of the bouquet then tapers downwards with flowing foliage, floral streamers, or ribbons at the bottom. This bouquet can be designed very dense with flowers and foliage or can be more loosely arranged for an "airy" or "wispy" look.
Crescent Bouquet
There are two types of crescent bouquets, symmetrical and asymmetrical. A symmetrical crescent features a balanced look with arched blossoms and foliage of the same length on both sides. An asymmetrical crescent features arched blossoms and foliage of different lengths so that one side of the bouquet is longer than the other.
Heart Bouquet
A romantic, alternative shape bouquet featuring two full arched shapes at the top while tapering down to a point at the bottom of the bouquet. .
Basket Bouquet
Flowers arranged and carried in a shallow basket and often used in a garden or garden-like wedding setting. Most often carried by young attendants.
Single Stem Bouquet
Single stem designs generally feature a unique design element, such as an intricately wrapped stem (for a long-stemmed flower), elaborate bow, streamers, or a decorative lace bloom collar (for a shorter stemmed flower) to give the design more interest and appeal.
