How do i sell my wedding dress ?

Hello all you lovely Brides to Be,

My Fiancé and I have made the difficult decision to cancel our wedding.

We postponed our original wedding date from 29/08/2020 to 18/09/2020 but all this back and forth of will we be able to get married has definitely taken it's toll on us both, particularly me.

We've begun the process of cancelling everything today and while most places have been really accommodating to our decision my wedding dress boutique has a policy where nothing is refundable meaning I have to pay the balance on my dress and collect it.

I understand their point of view, they've ordered my dress from the designer and it's since been discontinued. They no longer hold the sample size so they're unable to sell this on.

I'm now faced with paying and collecting a beautiful dress that I'll never wear, as if I wasn't heartbroken enough as it is.

I'm looking for advice as per selling this dress. I've had a little look at StillWhite and other pre-loved wedding dress sellers but I'm not sure what kind of call there'd be for a plus size (Around a UK 24) there'd be.

Has any had any experience selling a plus-size dress online?
