When thinking about choosing a bridal bouquet, I think it's really important to think about the overall style of your wedding and the overall feel that you want to have. Is your wedding more old-fashioned and romantic, something vintage, or are you going for a look that's sleek and modern and clean? You can use palette to guide your selections.
So thinking about whether you want something monochromatic like all white or all peach, whether you want bright colors? Do you want interesting textures in your bridal bouquet? All of these little decisions can be made, and can contribute to having a bridal bouquet, that really goes with your wedding. Another way to select a bridal bouquet is to think about the venue.
If you're getting married in the summer, outside by a lake maybe you want something that's going to be much more casual, kind of a gathered wildflowers look. Are you going to be married in a very formal, ballroom kind of a setting, so you want something that's going to be tailored, with really upscale flowers? These are ways that you can think about choosing a bridal bouquet.
