I think this may be one of those times when we are tripping over words.

To most people the words Ladies Sash could mean anything from a very small shoulder sash about 5" X 24" to a short sash about 9" X 54" also worn draped over one shoulder, up to a long sash about 11" X 110"worn over one shoulder and pinned at the opposite hip.

If you are talking about a sash worn by a man you are usually talking about a pipers sash. These are huge and take almost as much fabric and time to make as a kilt.

I could help a bit more if you could describe a little better what it is you are looking for. Do you have, or know of, any pictures of what you are looking for?
