Since butterflies are said to represent beauty and new life, having a butterfly-themed shower (and a purple one at that) could certainly celebrate both!
Look for invites with butterflies on them to set the tone. You may have to do a bit of searching here, but there are plenty of customizable invites that could be geared towards a baby-shower for pretty reasonable prices.
White or lavender table-cloths with fresh cut flowers will spice things up nicely. Incorporating vases with shades of purple in them along with rich purple votives is a simple way to keep with the theme.
For the menu, consider an exotic fair such as spicy Thai-salad with vegetable spring rolls served on a bed of purple cabbage leaves. You could also consider having a dessert table filled with different shades of purple delights (a la Amy Atlas) for guests to choose from. Top it off with a butterfly themed-cake or cupcakes with edible butterfly toppers- which could also serve as centerpieces.
For favors, crystal butterflies are not only dainty, but will help guests to recall the symbolic meaning of this beautiful gathering. And when all is said and done, the guest of honor will be floating on air as if she, herself, were a butterfly!
