April Wedding Ideas

Obviously pastel colors..bright colors would look nice. Yellow/orange, yellow/pink
Lilac/cream, pink/green...do spring flowers for your bouquets...roses, tulips, lilies, daisies..etc.
You can search for flowers or bridesmaid dresses you like and work off of that.
Since it is going to be april..depending on where you live..could be breezy. Maybe a wrap with the dress (mid to long in length). You might want to pick up the march/april bridal guide to get ideas.
