I think your listings look quite good. Some suggestions: you have 12 photos free - use them. Take lots of shots from different angles, crop your photos so they fill the photo box, zoom in on particulars.
One of your description lines is indented: "Note the measurements provided" - sorry, these things jump out at me!!
Also, watch your sentence construction, eg
"A bit of natural wear on the hems and the style of jean has some wear around pockets." - I'm not sure if you mean that there is wear, or that the jeans are styled like that. If it's a bit of both, separate your comments into 2 sentences. Be very specific.
Be careful what you say - don't appear to apologize or justify your charges, eg
*US buyers, please know that we are located in Canada, and ship via Canada Post Corporation, as you can see by the pricing, it is more expensive than that of the USPS which is not available to us. We ship all packages with tracking numbers for your protection, as well as our own. We would like to get your packages to you in a secure and timely manner but have no alternative when it comes to shipping methods and costs are non negotiable…thank you*
I would omit this. If you think that the shipping cost will put off many buyers, hide some of it in your starting price. Set up "cookie jar insurance" and ship lighter items by Light Packet Air or Small Packet Air. Most mail gets delivered. Out of 936 transactions world-wide, I have had 1 claim of non-receipt, and I actually doubt that that one was valid, since that particular transaction seemed doomed from the start. I rarely use tracking unless the weight of the parcel requires it.
You seem to be off to a good start - Good luck!!
