Here are some examples under $250.
This Banana Republic silk taupe dress would be great on a petite frame, softened by a lush bouquet of pink flowers. $250. Bouquet from Instyle Weddings
BR Monogram criss-cross silk dress is available at Banana Republic, $250, and would look great with a bouquet of cream flowers tied with black ribbon at a sleek affair. Bouquet from Martha Stewart Weddings.
This low-key but fun dress from Banana Republic reminds me of a garden wedding. I've paired it with a fresh garden bouquet in neutral colours from Nicolette Camille.
