ok - well photos could be much better. Plain background, straight on, full frame of the whole item. Close ups as extra yes, but the main pic needs to be zoomed right in and full of the whole dress, not the rest of the room/door. Your photos do not do it justice. Have you got a nice wooden hanger instead of a plastic one? Just hang it on a picture hook infront of a plain wall if you don't have a dummy. And lots of measurements too.
This is a much better pic - see the difference. Plain background & zoomed in. You don't need a photo of the surroundings, potential buyers just want to see the item.

And that light fitting you are selling - many carriers will not cover you for breakages against glass so you will need to investigate that. And the pic of the boots with the grip hanger - I would worry those grips would have damaged the boots so I wouldn't bid on them - sorry.
And remove the no returns - worthless and makes you look obstructive.
And never ever end auction listings during the day - 8-9pm Mon & Tues nights is best. You can schedule for free now. During the day ending is pointless. If I were you I would amend your listings to buy it now with best offer, use Hermes and get much better photos.
Also all your postage costs are v erratic - some ok but others too much. If items are under 1kg you can send tracked for £2.98 with Hermes. And please use your own pics not generic ones (especially for the main photo).
And Hermes takes 4-5 days - why pay for RM signed for, it isn't quicker if they don't bother getting a sig and the buyer claims they didn't receive it. Plus it doesn't offer enough insurance does it?
