I tried this jacket on today in a size down (size 8 from my usual size 10) and it was still pretty roomy. I'm certain I could easily size down to a 6 in this (shocking!) and it would still have a relaxed look to it. I didn't hate this jackets cut, and seam details, but the material is really light weight for Lululemon's typical glyde fabric, and it is very matte and wrinkly. I don't mind the matte look of it but the wrinkled look of the fabric really bothers me. I've also noticed this tendency to wrinkle with the On The Fly Pant in Deep Olive. The OTF pant is made of a stiffer version of full on luxtreme and at the lower leg it was very creased.
