Radiant Bride with Shoulder-Length Down Hairstyle and Blue Eyeshadow
She has her hair down but partly tied back right across from her ear level. It's a very easy bridal hairstyle—easy enough to do yourself.
You may not want your roots to be showing, though, at your wedding, even if you like this style. The very dark ends look okay, but the high-contrast roots are a problem, unless you're deliberately going for that look. Some women like it; others hate it.
