Can't stop gushing about (and staring at) the gorgeous new bling on your finger? There is nothing more joyous than that moment when you say "Yes!" — and nothing more stressful than the second that follows when you realize you've got a wedding to plan. While we can't make sure your cake is the right flavor or the flowers arrive on time, we're offering up our services in a way that will, at the very least, guarantee your makeup and hair look FLAWLESS. And, let's face it, that's the most important part. We teamed up with Simon G. Jewelry to bring you our first installment of Bridal Prep School. From the perfect time to book your spray tan to when you should start your at-home teeth-whitening regimen, we've mapped out your month-to-month bridal beauty countdown so that you'll look perfect on your big day — even if the tablescape does not.
