Short answer
Lululemon tops: what we know so far.
Runs true to size across most ranges. The Align runs slightly small and is low-compression — not a performance legging. Offers inseam length selection (23", 25", 28") which is rare and essential for petite women. The Wunder Train is the go-to for higher-impact activity.
Watch out: Align goes sheer in light colours and during sweaty activity. Wunder Train can be tight in the calf for muscular calves. Premium price makes sizing mistakes expensive.
