I really love the fit of this jacket. I got it in my normal size 4, and it's a body skimming fit but not tight. It definitely does not look as loose on me as it does on the Lulu model, so not a size-down item. I don't think this model does justice to most of the things she models. Maybe they just dress her one size too big or something and she's a little too skinny with a pretty flat chest, but I never really like anything on her.
I think brushed luxtreme is a great material for jackets. I only have one jacket in brushed luxtreme (Lift Your Spirits) and every time I put it on, it's so soft, stretchy and warmer than it looks. This jacket actually has quite a bit of detail. The under arm and upper back areas are mesh, as you can see from the photos, which will keep your sweaty areas more ventilated. The stripe that goes down the back is a cute mesh design as well.
The arms are actually wider fitting than most of my other Lululemon size 4 long sleeve items. It's great for moving, you can raise your arms and swing them around without feeling constricted. The cuffs have a stripe of reflective band on the inside so you can flip them up to make use of that. Or leave the cuffs down to have less of an athletic jacket look. It's a great idea! The zippers are like the old plastic ones they used to use. The length is great, and it's just a winner overall!
Here it is on me:
I don't usually gravitate towards colorblocked items, but I like this one. I also like this jacket in dune and bleached coral. But I didn't have a choice since that one only had size 8 and 10 left when I looked. I would get the black one in this as well if I didn't already have my Lift Your Spirits jacket in black and same material! But if you don't, I think it would be a great basic black jacket to have.
