I don´t understand either why people would buy Zara second hand but hey.
I think the pricey items don´t go as fast because when I buy an item without seing it IRL and without the possibility to return if it doesn´t fit....so I´m very hesitant to pay more than 200€ for something I´m not sure will even fit...its a gamble. and let´s be honest some of the photos are really bad and sellers don´t even want to post pictures of the items on.
But this season´s items are listed at very close to retail price usually...
I get that, but if you get every possible measurement, and my more expensive items tend to be shoes and bags, and the odd dress, but then I really give every measurement (armpit to armpit, 10 cm under the armpit, waist, shoulder width, you name it) and if you pay 200 to 500 for an item that usually retails for 2K plus up to 8K (a red carpet dress you can only wear once and it is usually for 3 to 5 hours max) it is still one hell of a bargain. I honestly do not list anywhere close to retail (and I feature in the discount I get from the designers as it will be worn at an event where their name is then mentioned - unfortunately I am not in the league where it comes totally free) but I am seriously not going to let it go for the price of a H&M t-shirt in the sales.
In all honesty, I often tried to post additional pictures on VC, what happens is that they can't be bothered to upload them, so I tend to have them on another website and then "hint" to the interested party that they might want to google the description and will get more pictures.
