I know that you may have heard differently — that size doesn’t matter (no, I’m not talking about that!)  — but that really isn’t true: when it comes to the size, or length, of your prom dress this year, it really is a big deal.  For one thing, a prom dress that is too long will probably be too heavy to move around in comfortably, let alone to dance in.  A longer prom dress will also undoubtedly be much too hot — and you don’t want to be perspiring excessively on the most important night of your young life.  So consider the length of your prom dress — size really does matter!
