I'm reviewing 4 different types of leggings. Hope this helps someone!
Black Label Signature 380N Leggings Jessi Rose - Fabric feels soft to the touch. Tight & supportive fit but not uncomfortably restrictive. There's a thin elastic band at the top of the leggings (inside the fabric) that digs in at your waist but will hopefully loosen over time. Not as buttery soft or flexible as Lululemon Aligns.
Black Label Signature 360N Leggings Wind Gray - Soft to the touch. Significantly less restrictive than the 380N. Good for yoga since it feels very flexible. Wind Gray is a solid light gray color--much less purple-toned than the 380N Aurora Gray appears on the website.
V-Up 3D Plus Leggings Walnet Beige - Feels slightly rough to the touch, kind of like a polyester sweat-wicking material. The walnut beige is a light cocoa color with a hint of light purple mixed-in. When you move, the legging material stretches but doesn't 'move with you' like the 380N and 360N. Feels cheaper than the others (makes sense considering that this is their cheaper, flagship option).
XELLA Intention Leggings Moroccan Navy - Feels slightly rougher to the touch than the 380N & 360N. Much darker than the photos demonstrate. More of a deep, dark navy color--nearly black. Seems slightly see-through when squatting. Very thin fabric. Probably my least favorite due to the dark color & thinness. (This color looks much darker in person when compared to my photo. Its more like an ink blue navy color.)
I'm 5'3" 112lbs with a slim build (28" waist and 35" butt) and the size Small in all types fit me well. The length on all 4 types fell a couple of inches above the ankle (none were full length or reached my ankle). The length for all 4 was closer to a US 7/8-style legging.
FYI: If your color/size is out of stock in the 1+1 listing, try searching for the individual listing for that item. You may not get the best deal but you might find that your color/size is actually in stock in the individual listing.
