First time selling items on ebay..help? :[?

I wrapped up a skirt and took it to the post office to weighed and it came to 385g and the post office guy said it would cost £2.70 for UK delivery.

Now i have not posted this item on ebay yet because Im not sure about the post and packing, because i do not know who is gonna buy it and where in the world they are.

What do I write on post and packing? :(

Actually all you need is the size and weight of the package and ebay will take care of the rest charging customers the proper postage based on both your and buyers location and weight and size of the package.

It has a built in shipping calculator.
