V-Necks Lengthen
A vertical line pulls the eye downward, narrowing whatever it crosses.
Free AI Tool — V-Neck to Turtleneck
Neckline Guide
A neckline guide is an AI tool that maps your face across 68 landmark points to measure its shape, then matches that shape against the necklines — from a deep V to a full turtleneck — that balance it best.
Swap one top for another and nothing about your bone structure moves, yet the face underneath can read longer, rounder, or sharper depending on where the fabric ends and your neck begins. Upload a photo and see which collar line your jaw calls for.

How a Neckline Frames a Face
Change a crew-neck sweater for a deep V and nothing about your jawline shifts — but a face that looked heavy a minute ago can suddenly read longer. That's the neckline doing more optical work than anything else in the outfit.
No other seam sits this close to your face. A neckline shares the same visual field as your jaw and cheekbones, which is why it changes how that shape reads more than a jacket, a bag, or a pair of shoes ever will.
Boat Necks Widen
A horizontal line broadens the shoulders and, by the same trick run in reverse, shortens the face sitting above it.
Scoops Soften
A curved edge offsets an angular jaw without fighting it for attention.
Convention, Not AI
The face-shape reading is fully automated. The styling logic attached to it — which line suits which shape — is written by a person, not generated.
Face shape decides plenty, but not everything a neckline has to answer to. A pear-shaped frame carries its own neckline logic that has nothing to do with jaw or cheekbone width, and our silhouette guide covers that other half of the decision.
Every Neckline Against Every Jaw
What does a boat neck do for a square jaw versus a rounder one? Your own scan answers that question for exactly one face. The full side-by-side guide answers it for every shape at once, so the reasoning behind a recommendation is visible instead of something you're asked to take on faith.
Run Find My Neckline below for your own result, or scan the full breakdown first if you'd rather see the logic before the algorithm hands you an answer.
Choosing in
the Shop
A neckline answers to your face and your frame at the same time, and the reading you take into a store is only as good as the photo it came from.
Square to the Camera
Turn your head even slightly and the width readings the whole scan depends on shift with it.
Hair Off Your Face
Jaw and temple points need a clear line of sight — hair, a hood, or heavy bangs block landmarks the same way a mask would.
Even Lighting
A shadow along one side of the jaw is the single most common reason a scan lands on the wrong shape.
A Starting Point
Everything here is convention, not law. If a neckline photographs badly on you despite matching your shape on paper, trust the mirror over the chart.

Why the Neckline Beats the Rest of the Outfit
A belt sits at your waist. Shoes sit at the floor. A neckline sits an inch below your chin — close enough that your eye reads it and your face as a single shape rather than two separate elements.
That inch of distance is why a boat neck can widen a round face in a way a wide belt structurally can't. The horizontal line falls inside the same frame as your jawline, while a belt sits far enough away that your eye processes it on its own.
Earrings sit even closer than a neckline does — right at the jawline itself. The earring shape guide runs the same shape-matching logic on that smaller, closer piece.
Face Shape and Body Shape Together
Neckline advice shows up in both face-shape guides and body-shape guides, and the two don't always agree. A pear-shaped body benefits from a boat neck because it broadens the shoulders — a round face does not want the same thing.
When the two conflict, the face usually wins for anything worn near the collarbone, simply because that's the part people look at first. Our silhouette guide covers the body-shape half of that same decision.
About This Tool
The face-shape reading behind this page comes from the same in-house model used across the site — Ahsan Fayyaz trained it on real faces and benchmarked it against other face-analysis tools rather than licensing one ready-made. The styling guidance itself is written by people and matched to your measured shape by convention, not generated by AI. It's an informational styling tool only, not medical, clinical, or professional advice.

Frequently Asked Questions
It places 68 landmark points on your photo, measures the proportions between your jaw, cheekbones, and forehead, and matches that shape against a set of neckline categories written by hand. Three named options come back as your result.
Yes — it's the same 68-point landmark map used across every face-shape and styling tool on the site.
No. Two free scans a day work without one.
Two, no sign-up required.
No. Your photo is processed by our own model, not sent to a third-party AI service, and deleted from the server right after your result is generated. What you see on screen afterward sits only in your browser's cache — refresh the page and it's gone for good, on both ends.
Three named options, sized for bringing straight into a fitting room or handing to a stylist.
Rerun the scan with a different photo — angle and lighting shifts can nudge a borderline shape reading enough to change which necklines come back. And remember the guide is a starting point: personal taste is allowed to override it.
Both, and more than people expect. Hair covering your jaw or temples hides the landmarks the model needs, and shadow along one side of the jaw is the single most common reason a scan lands on the wrong shape.
Not entirely. It gives you three names to say out loud in a fitting room instead of guessing, but a stylist can see fit, fabric, and color in ways a photo of your face never will.
Not into this specific result — this tool reads face shape only. Body shape runs through a separate logic covered in our silhouette guide, and the two can occasionally point in different directions for the same person.
Yes. The earring shape guide applies the same face-shape matching to a piece that sits even closer to your jaw than any neckline does.
Most faces don't sit at a perfect category boundary. The model returns whichever shape your measurements land closest to, and the neckline advice attached to it still holds even if you're a borderline case between two categories.
Yes — screenshot or note your three results before you start browsing, since you won't have the tool open in a fitting room the way you would at home.
Usually. A filter that slims your jaw or enlarges your eyes edits the exact measurements this tool reads, which can shift which shape — and which necklines — you get matched with. An unedited photo gives the truest read.
Rarely by much. Bone structure doesn't change between photos, so two shots of the same face — one bare, one styled — typically land on the same shape or a neighboring one, unless angle or filters distort the measurement.
No. Face-shape detection is automated; the neckline recommendations attached to each shape are written by people, following established styling convention rather than being produced by the model.
Yes. The measurement and the neckline categories both apply regardless of gender — a V-neck lengthens the same way on any jaw.
Yes — your result can be shared as a styled image without needing to take a screenshot.
Yes, any time, using either of your two daily scans. A haircut can change how a face looks day to day, but it won't move the underlying jaw and cheekbone measurements the guide is built on.
