ok got to do bedtime soon so will be brutally honest and hope you are not offended.
put a higher price on it. i would assume something is wrong with it at that price.
lots more key words required in title
why is it unworn? obv if for a not good reason dont say but if it wouldnt put people off say why
lots more pics needed, get close up of the fabric, the bodice on its own, the detail on the bodice. put them on photobox or similar and you can put the image directly into the text at no extra cost.
you sound unsure of yourself and this comes across as negative. how do you know it is silk? why doesnt the label say so? state some thing like 'bought in sale so no label, this is 100% silk'. nothing negative, no ifs or maybes, you are sure of what you are buying. rewrite the bit about slubs. this is a natural part of the fabric, dont say it might be faulty!
no need to mention it may crease in post, maybe say how you will send it then people will be aware it could happen
i read ex sample and thought shop soiled. was it in a sale? would be a better way to say it, even if the reason it was on sale is because it was ex sample.
your feedback % isnt great because of one remark as a buyer. sell yourself - you have 100% positive feedback as a seller! this will make people more confident
get a paypal account where you can accept card payments. i always fund with debit cards. i wold see that and think too much hassle. could you use your dps / friends / mums account?
like i say i hope you are not offended. it looks lovely but honestly i would be put off bidding for above reasons. be positive!
