Lululemon vs Amazon. I love this sold out Cerulean Blue color leggings and bra from Lululemon and I found the same color on amazon. The amazon brand has so many styles that look identical to lululemon. I have been wearing this brand for over five years and the quality is amazing! The color is called Blue Waves and I like it even more than the Lulu blue. I am 5’9” and wearing the 28” lululemon aligns and 28” in the amazon brand too. The amazon brand comes in sizes XXS-XL. The fabric from Lululemon is 81% Nylon, 19% Lycra elastane and the fabric from amazon is the exact same 81% Polyamide, 19% Lycra. Nylon is a type of polyamide.amazonfinds lululemon workoutset LTKWatchNow LTKActive LTKStyleTip
