The long-sleeved floral wedding dress combines a V neckline with fine sheer-looking arms. The sleeves gather near the wrists and widen at their ends. The long front skirt follows the body more closely, while a broad train spreads behind. A high leg opening comparable to the three open-skirt references is not clearly visible in this view. Hair worn up leaves the neck area easy to see.
Compare this more closed front line if you are uncertain about exposing the leg. You can enjoy a train and the widening lower shape without choosing a high slit. Decide about the front skirt first, then assess the additional sleeve coverage. Otherwise you might attribute the whole difference to the covered leg when the sleeves are actually the feature you prefer.
Try your shoes under the more closed front edge of an actual candidate too. Walk in them and assess your own skirt length before discussing alterations. Plan the handling of the trailing fabric separately for the evening. A closed front view does not automatically answer how the train should be worn during the later parts of your day.
