We are happy to have it!
It feels very well tailored, the zip goes very easy and it fits very tight. We both love the puffy sleeves.
Just for the neck part i recommend to make a special request if it shall be made-to-measure. My wife got a rather short neck and it is a little too high.
We have a lot of zippers on our products here and a lot of options for zippers. A lot of times our patterns come with a pre-set selection, but we can customize more. Locking, WaterTight and even air-tight zippers are sometimes requested as customization features. You can always ask for a quote for something via the "I'd like to customize this product" link on any page. Meanwhile, here's a simple picture to explain the type of zippers and what they are called.
