Ask any bride (or her parents) about buying a wedding dress and you’ll likely hear the same thing: Wow, those things are expensive. How expensive? Some — even some featured on the popular cable television show “Say Yes to the Dress” — can run into tens of thousands of dollars. Thankfully, the average dress price is much lower — about $1,600, according to a survey last year conducted by The Knot. Accessories (veils, shoes, lingerie), can bump up that price by hundreds more.
