A halter neck dress refers to a dress style that has straps or fabric that wraps around the neck, leaving the shoulders and back bare. In this case, the dress has a halter neck design combined with a gold necklace. The dress is also described as a hi-low dress, which means it has a shorter length at the front and a longer length at the back, creating a stylish asymmetrical hemline. The dress is made from faux tencil, a fabric that mimics the look and feel of tencil but is not made from the same material. Overall, this dress combines a trendy halter neck style, a gold necklace accent, and a fashionable hi-low hemline, all in a faux tencil fabric.
