To Wear

[Bobbert]

I was selling a pair of denim shorts and a shirt today and the person who wanted to buy them spoke almost no English. Everything went fine until I wanted to say:

The denim shorts have never been worn
and
The shirt has only been worn once

For the life of me, I couldn’t form a way in my mind of how to say it, so I just said, "Son casi nuevos," but that’s not what I wanted to say.

How should I have said the above? Even now when away from the pressure of speaking in person and needing to form a sentence on the spot, I’m still totally unsure?

If I would have said the following, how close would I have been?

Los pantalones cortos de mezclilla nunca se han sido llevados puestos

La camisa ha sido llevado puesta solo una vez

Any input is appreciated.
