You ARE sexy. I know your arms are bigger than they used to be. And maybe a few other places have grown more than you expected. You are a woman carrying a baby and that’s a beautiful thing. Not only that but look at your breasts! Certainly you didn’t have THAT kind of cleavage before! Not to mention your glowing skin and beautiful shiny hair.
The trick to feeling and looking as sexy as can be on your wedding day is to wear a gown that showcases your best featured that you do enjoy and are comfortable with. Consider showing off your decollete with a low neckline or opting for a slightly lower cut back. You don’t have to hide your belly, or your arms- just bring the attention to the places you enjoy these days.
Also I recommend wearing flats. Ok typically heels are sexier, agreed. BUT there is nothing sexy about tripping or getting swollen feet half way through the reception and having to trade those heels for fuzzy slippers. I know, because that’s what happened to me! 
I love this blog!! Finally a blog for expecting brides! Thanks Jessica!
