Wedding dress necklines

While we're on the topic of weddings, I've been thinking about dresses recently. Specifically, necklines. One of the things I've noticed is that an off-the-shoulder style tends to suit me in general. And I also love sweetheart necklines. And the amazing thing about wedding dresses is that a lot of the off-the-shoulder ones have sweetheart necklines. So I could have BOTH. Like this:


Or I could even have one that is just plain off-the-shoulder, without the sweetheart, like this:


Or is the whole off-the-shoulder thing just way too eighties and something I'll look back on and shudder? Because I could also go for a strapless sweetheart neckline, like this:


I know I've talked about wedding dresses before, and you guys have already given me so many helpful suggestions and opinions. But I can never get sick of dress shopping, and since I can't actually really go try on the dresses for at least another few months, the online admiring and agonizing over style choices is all I have to sate my desire at the moment. So please, bear with me. And tell me your thoughts.
