Lanvin $2.5K embellished dress 36 US4 NWOT

This dress is a leftover from my online designer store, it is highly reduced and original, The price was close to $3k with tax in Canada, i bought it on sale for $750, selling it very cheap because it is from 2012 collection (but timeless like all Lavin clothes and was not worn) and has a very slight lighter discolouration on top of shoulders my guess is it was exposed to sun in a store?? It is not visible when you wear the dress. There is a picture showing this small fault and also i included inside tags to prove the authenticity. It is a simple shape dress which supposed to fit loose with two pockets in the front done in a washed down black color and made of 58% linen and 42% cupro. The fabric has a distressed and more casual look, it is beautifully combined with a rich a bit shiny embellishment around the neck which make this dress quite stunning and unique. The size is 36 French which would translate into US4/6 please check the measurement. Chest-18", hips-18.5", length-35"
