It was an event where Lululemon offered people a chance to swap their Lululemon dupes for a free pair of authentic Align leggings at Century City Mall, Los Angeles. A YouTuber who was present at the event narrates her experience: "I waited 4 hours in line for the Lululemon align legging dupe swap […]" "Basically anybody can come and swap in a pair of leggings which could be from any brand and they will give you the align legging which is their most popular style." "This is my first pair of aligned leggings so I had to try them on and this fitting room was massive but this is what the leggings look like on they're very snatchy and they're full price 98 dollars so I think it was worth it." In comment replies on their TikTok announcement video, Lululemon hinted future plans of hosting this event in other cities and may probably be swapping other products besides their signature Align Leggings.
