Quick Answer: Sarah Lynn’s costume comes down to the mismatched skull shirt and the drawn-on freckles.

  • Maybelline Sensational Red Lipstick
  • Brown Eyeliner ( To Make Freckles) (essential)
  • Gold Sneakers

Sarah Lynn performs for a living, on stage, in interviews, at parties, and rarely stops long enough to be anything else. The mismatched skull-and-stripe shirt is the one piece that actually identifies her, since a plain pop-star outfit could belong to a dozen other characters. Kristen Schaal voices her for the whole run of the show (Wikipedia), and her storyline is widely considered one of BoJack Horseman’s strongest, so most people who’ve watched even a season or two will recognize the look.

  • 1 Sarah Lynn Skull Shirt (essential)This is the single most identifiable piece of her wardrobe. The real shirt splits into two different patterns, a white skull print on one side and lavender stripes on the other, mismatched on purpose. If you can only get a plain skull-print top, that still works better than skipping it entirely, since the skull print alone is the detail people will clock first.

  • 2 Denim ShortsBlack denim short shorts, plain and worn. Check your closet before buying a pair specifically for this.

  • 3 Metallic Eyeshadow PaletteGo for a slightly smudged look rather than a clean application. Her whole appearance reads as someone who got ready fast and has been out for a while.

  • 4 Maybelline Sensational Red LipstickBright red, applied a little imprecisely rather than perfectly lined. Precision isn’t the point here.

  • 5 Brown Eyeliner ( To Make Freckles) (essential)Freckles across the cheeks and nose are one of her defining features, so this is doing real identification work, not just adding texture. Use small, uneven dots rather than a scattered spray, since real freckles cluster instead of spreading evenly.

  • 6 Gold SneakersHer actual sneakers in the show are yellow, not gold, so this is a close color swap rather than an exact match. Any high-top sneaker in that general color family works.

How to Style the Sarah Lynn Halloween Costume

The shirt is the first thing people register, and if it’s a single clean pattern instead of two mismatched halves, the whole look drifts toward generic pop-star costume instead of this specific character. The freckles matter more than people expect, since a bare face loses one of her most identifiable features. At a party the red lipstick and smudged eyeshadow are what carry the look once the shirt gets covered by a jacket or a crowd, so if you skip the makeup, you’re left with a mismatched shirt and not much else pointing to her specifically.

She casually corrects people on architectural terminology mid-conversation, joists, load-bearing walls, things nobody expects a pop star to know off the top of her head. It’s one of the only moments in the show where she sounds completely sure of herself about something real.

Set the freckles so they don’t smudge

Drawn-on freckles smudge fast if you’re sweating or touching your face a lot, so set them with a light dusting of translucent powder once you’re done. Check them in a mirror partway through the night, since uneven freckles read as smudged makeup instead of an intentional detail.

Have a strong opinion about the venue’s architecture

If someone compliments a building, a room, or even a stage setup at the party, launch into an unprompted, oddly technical opinion about the structure. It’s a small, specific bit that’s funnier the more confidently you deliver it.

Couples Idea

Sarah Lynn & BoJack Horseman

Might work, but their relationship in the show is genuinely difficult, a father-figure dynamic that becomes something else entirely, so calling it a couples costume glosses over what actually happens between them. The visual pairing works fine, her bright, mismatched pop-star look against his flat gray blazer, but it’s worth knowing what you’re referencing before you commit to it as a fun couple’s bit. BoJack’s page has the build if you want that half done right.

Duo Idea

Sarah Lynn & Todd Chavez

Strong duo. They’re both bright, chaotic presences in the show with color palettes that contrast well, her lavender and gold against his red and yellow. Todd’s page covers his build if you want the full list.

Group Idea: BoJack Horseman Main Cast

Sarah Lynn, BoJack Horseman, Todd Chavez, Princess Carolyn, Diane Nguyen, Mr. Peanutbutter

Excellent group. Todd’s link is already used elsewhere on this page, so here he’s just a name. BoJack, Princess Carolyn, Diane, and Mr. Peanutbutter round out the main cast, and the range across a slouched horse, a sharp-dressed cat, a plain-dressed writer, and a golden retriever-coded dog keeps five people from blurring together.

Group Idea: Fame Has a Price

Sarah Lynn, Ashley O, Jackson Maine, Nina Sayers

Strong group thematically, all four characters explore what fame costs the people living it, but the visual range is wide enough that the connection only lands if you say it out loud. Ashley O’s pop styling, Jackson Maine’s rock-musician look, and Nina Sayers’s ballet costume don’t share anything visual, so this works best as a deliberately curated group for people who already know all four stories rather than something that reads at a glance.

Sarah Lynn Halloween Costume DIY Tips

Building the Look

Most of this is drugstore makeup and closet basics except the shirt, which is worth getting close to the real pattern.

  • Shirt: buy this one, or find a plain skull-print top if you can’t get the split pattern exactly.
  • Shorts: check your closet first, plain black denim shorts are common.
  • Eyeshadow: any metallic palette works, smudge it slightly rather than blending it clean.
  • Lipstick: buy this one if you don’t already own a bright, true red.
  • Eyeliner for freckles: buy this one, it’s cheap and it’s the detail that actually identifies the character.
  • Sneakers: check your closet first, any yellow or gold high-top gets you close enough.

Playing Sarah Lynn at the Party

She talks loud, moves fast, and has genuinely strong opinions about buildings that nobody asked for.

  • When someone asks who you are, answer with way more energy than the question needs.
  • If someone compliments the venue, correct their assumptions about the architecture, confidently and at length.
  • Say “That’s too much, man!” about something that is, in fact, not that much.
  • Keep the energy up all night. She doesn’t really have an off switch, and that’s the whole bit.

Sarah Lynn Halloween Costume: FAQ

Wear the mismatched skull-and-stripe shirt with black denim shorts, add gold or yellow sneakers, and finish with red lipstick and drawn-on freckles. The shirt and the freckles together are what separate this from a generic pop-star costume.

Yes. BoJack Horseman ended in 2020 but stays in steady Netflix rotation, and Sarah Lynn’s storyline is widely considered one of the show’s most acclaimed. Anyone who’s watched even a season or two will likely recognize the mismatched shirt and the freckles.

Two lines cover her well: “That’s too much, man!” her go-to reaction when something’s genuinely over the top, and “I wanna be an architect,” one of her quietest and most memorable lines, which reveals the one thing she actually wanted for her life.

A plain skull-print top works if you can’t find the split pattern. It won’t be exact, but the skull print alone still does most of the identification work.

Messy, slightly. Her whole look reads as someone who got ready fast, so a perfectly blended, precise face works against the character rather than for it.

No, uneven is more accurate. Real freckles cluster instead of spreading in a neat pattern, so a slightly random placement reads better than symmetrical dots.

The outfit itself is fine, just a shirt, shorts, and makeup. Her character has some heavier themes in the show, so keep any in-character bits light and skip anything referencing her more difficult storylines if kids are around.
