Indigo reviews the Stay In Line Lip Liner in the shade Leave me alone by Jason Wu Beauty. They love the color, describing it as a dark brown with a rosy tint that complements their skin tone. Indigo is excited to try it with an ELF gloss in their next review. Overall, the lip liner seems to be a great product, offering a unique and flattering shade. However, without further information, it is difficult to assess its longevity, ease of application, or other potential drawbacks. Nonetheless, based on Indigo's positive comments about the color, it appears to be a promising lip liner option.
