Different kinds of halterneck dresses.
Neckolder dresses are not all the same. There are very different cuts that all belong to the main category of halterneck dresses. The classic of course being the halterneck dress with two straps that are tied behind the neck, covering the breasts. A slightly alterated version is the round halterneck, with both straps sewn together (thus not being size-adjustable), so you have to slide in with your head between the straps. Another version is the halterneck, with the two straps originating in the middle of the dress and then being tied around the neck. The so-called collar halterneck is also a special halterneck design. Here, the straps is tightly placed around the neck, so there is no décolletage; a very sporty halterneck-version.
