Lululemon leggings in size 4 are designed for a snug fit, typically suitable for individuals with a waist size of 25"–26" and hip size of 34"–36". They often feature a high-rise or mid-rise waistband for comfort and coverage, with options like buttery-soft Nulu fabric for yoga or more compressive Everlux fabric for intense workouts. Many styles include functional details such as hidden pockets, flat seams for reduced chafing, and a four-way stretch for maximum mobility. Lengths to 31" (full-length) to cater to different preferences.
