The Free2Be is the most flattering style with the line/pocket details in the body and the very large off the shoulder hood that draws your attention up and to your face and neck. It looks best fitted so if you use two lululemon sizes I would go to your lower size. Fits nicely on the waist and when you layer it with a long t-shirt or tank it looks really cute. I got the black one a while back because I like layering it with all colors and it's been really versatile. Not a shleppy sweatshirt at all. Made of French Terry so it's a lighter weight cotton you can wear in spring/summer.
The Remix Lux is the same shape as the heavy Remix except it's very much thinner and cooler for summer use. It's made of Modal and lycra which makes it feel really silky almost slippery (not shinny though) and the inside is an almost velour like version of Modal. The fit is pretty strait from hip to underarm and if you want a fitted look go a size down. Because of the type of material it is you don't have to worry about it clinging to luv handles or anything like that, just that it fits in the arms and torso. The Lux is much coveted and hard to find but Lululemon seems to have been putting a few out the last two Wednesdays and they go super fast. Either they're coming out with new ones or they're going to keep releasing old styles on the website.
