Mac Duggal evening gown

I may have had some AI help on the description. 😂 Feel free to edit however you think will work best. I paid $479. What do you think is a reasonable price? I’ll take whatever I can get. Description: This Mac Duggal evening gown is an elegant floor-length design in a soft lavender color. The dress features a deep V-neckline and is crafted from a sheer sequined lace overlay. The bodice has a faux wrap design that creates an elegant silhouette, while the skirt flows gracefully to the floor with an approximate length of 60" from shoulder to hem. The long bishop sleeves are semi-sheer and unlined, creating a romantic look while adding coverage. The dress is fully lined through the bodice and skirt.   The dress is a size 16 and fits true to size. It is new with tags and in flawless condition.
