Baukjen ruched skirt... lovely but huge! Where to sell?

[jaws5]

I ordered the black Baukjen ruched skirt after reading reviews and it's really great: versatile, well made, flattering.... and huge! I was in a hurry when it arrived and wore it to the theatre but it is far too big in my usual 12 size, and cannot return it as I took label off and wore it. I then ordered a 10 and it's perfect, I love it! They're not cheap and I'd like to sell it but can't be bothered with EBay. Do you know an easier way to retrieve some of the ££?

Hardlyever worn it.com?

I'll look into Hardleyever.... thanks! Any other ideas?

I have the 12 in grey and the 10 in black, both from e bay, one was new with tags , one without but looked new. They go for about £20-25 usually. Agree they are on the large size, whereas Baukjen I find to be true to size slightly snug in most cases.
