You know when I was shopping for my first bbag, I was considering the Matelasse, but then after reading and reading and then some more reading, I didn't see too much love for the Matelasse, so I chose the Day instead. Now after seeing yours, but I'm looooving it! Your Ivory is . I've never seen it IRL though. Do you have a picture of it next to a City or Work? I know you said it FITS as much as a work, but I wanted to see the size comparison wise.
Here's my Ivory medium Matelasse next to a Steel City...
Also, I can easily fit it over my shoulder. It slides effortlessly over my shoulder even with a coat on. I can't do that with a City or RH Work.
