The lower left arm of Lavigne showcases a beautifully intricate and elaborate half-sleeve, which carefully ties together an assortment of tiny and large pieces she's accumulated over the years. "All of my tattoos for a good 15 years were just random," she explained about her half-sleeve in an interview with Inked Magazine. "I was probably super drunk, and I was like, 'Let's do this!' I never really thought them out. Then a couple of years ago, I sat down with London Reese, who is now the tattoo artist I have come to my house instead of going to some random tattoo store. I was like, 'Hey, I've got all these tattoos that go just about everywhere, can we bring them all together and sort of make it look like a half-sleeve?'"
Among the plethora of designs is a switchblade knife inked across the length of her forearm, which most likely symbolizes her strength amid her two-year-long frightening battle with Lyme disease, with which she was diagnosed in 2014. On the top corner of the knife sits a gothic cross symbol on her wrist, which she got in 2017. There's also a heart piece filled with red ink that says "MOM" on a patch over it near her wrist. It is a sweet tattoo that honors her mother who she's extremely close. To bring together her existing designs, Lavigne got done a music-themed half-sleeve. To deftly fill up the empty spaces on her sleeve, she added a microphone, several musical notes, and a large rose on the outside of her forearm that starts right below her elbow and extends up to her wrist.
