While video chatting with Pop-Pop, she disguises herself as Lisa to cover for her. When their parents found out about their little charade, their punishment was to go about their tasks while still dressed as the siblings they covered. Lynn had to continue training with her baseball team but couldn't hit the ball due to wearing Lisa's glasses, giving her a visual handicap.
Disguised as Lincoln, she wore his football uniform which was a red helmet with a yellow line that had the Royal Woods Rooster logo on it, followed by her wearing a red football with the number 1 on it and wearing white pants and white shoes identical to Lincoln's.
In the flashback, when the Loud kids are pretending to be pioneers in the time of the Wild West, Lynn is dressed like a cowboy, wearing a white cowboy shirt, a blue cowboy vest with a sheriff star, a red bandana, blue cowboy pants, with a black belt holding it, white cowboy boots, and a tan cowboy hat with a red band.
At times, her sleepwear consists of a tanktop and red shorts.
Other times, her sleepwear is a longer version of her jersey used as a nightgown. Both sets of sleepwear have socks.
Lynn wears her baseball outfit in this episode which includes a red t-shirt with a yellow line across the torso, and yellow lines on the sleeves, red shorts, and big red baseball cap with a big white section in the front.
