Size Guide · Fit begins at the cap

Your cap size is one number.

One measurement decides whether a wig sits or slides: the circumference of your head. Length, texture, lace and density are taste. This one is not. Here is how to take it, and what it means for the cap.

01 · Find your cap

Slide to your number.

Each collection has its own chart, so the same head can be a Small in one and a Medium in the other. Atelier ready-to-ship comes in Small, Medium and Large. Atelier custom has no sizes: it is cut to your own numbers. Choose one, then set the tape to your circumference.

02 · The charts

What each cap measures.

Circumference picks the cap. On the Atelier, five more measurements build it, so the cap follows the shape of a head as well as its size.

Atelier ready to ship · the Atelier chart, in inches. Each cap is made at these numbers. Circumference and front to nape can be taken in up to an inch, never let out; ear to ear does not change. Taking a cap in to your own number is a $10 add-on. Atelier custom is cut to your own numbers instead.

Between two sizes, take the larger. Give us your number either way: we set every Signature cap to your actual measurement, Extra small and Extra large included.

Every Archive piece is one of one, and its cap size is printed on the piece. Archive pieces are styled and finished before they are listed, and final sale: no cap, color or style changes, so ask us before you buy if you are unsure.

03 · With a tape

Four passes with a soft tape.

Use a soft dressmaker’s tape. A steel tape will not follow the curve of a head and will read short. Write the four numbers down: on the Atelier they become part of the build.

  1. 01
    Circumference: the one that sizes the cap

    Start at your front hairline, in the center. Take the tape back above one ear, around the nape at the lowest point of your hairline, forward above the other ear, and back to where you started. Keep it snug against the skull, not tight.

    • Read it in inches, to the nearest half-inch
    • Take it twice; if the two readings differ, take the larger
  2. 02
    Front to nape

    From the center of your front hairline, straight over the top of your head, to the base of your nape.

  3. 03
    Ear to ear, over the top

    From the top of one ear, across the crown, to the top of the other.

  4. 04
    Temple to temple, around the back

    From one temple, around the back of the head at the level of the occipital bone, to the other temple.

Measure it as you will wear it
On the day.

A wig cap, braids or a bun all add circumference, and they add it unevenly. Measure your head exactly as it will be on the day you wear the wig. If nothing goes underneath, measure your bare head.

Between two sizes
Choose by your number.

On the Atelier there is no in-between. Small fits 20.5–21.5″, Medium 21.5–22.5″ and Large 22.5–23.5″, and each cap is made at the top of its range. Wear it as made, or we take it in to your exact number for a $10 add-on. On Signature, take the larger and give us your number: we set the cap to it. A cap can be taken in, never let out.

Matched to your skin, not to a swatch chart.

Eight in ten of our orders have needed no cap-size adjustment. The scan takes the measurements; a person sizes every wig by hand before it is built. Rather use a tape? Enter your numbers by hand when you start a scan and we build to those.

05 · How a cap adjusts

A cap is not a fixed object.

Three things hold a cap on. Only the band changes its size, which is why the size you measure into matters.

01

Elastic band and strap

An elastic band around the back of the cap, with an adjustable strap to set it to your size. It takes up a little slack and gives a little under pressure.

02

Clips

Combs sewn into the cap that anchor into your own hair. They hold position rather than change circumference, so the cap has to be the right size to start with.

03

Ear tabs

Bendable tabs at each ear that keep the cap close at the sides. Like the combs, they hold position rather than change size.

Glueless wear

An adjustable band, no adhesive.

It comes on and off in seconds. Closures are usually worn this way; a frontal can be too, with practice. It is the easier of the two to learn, and the one to choose for sensitive skin.

Adhesive wear

Held at the hairline.

Held with lace adhesive or gel, for the longest hold and the cleanest melt. It is the method for a frontal in HD lace, and it asks more of you than a glueless install does.

06 · If it does not fit

A cap can be taken in.

Inside the first 30 days, cap size is a free adjustment on every Atelier and Signature wig, and a cap re-set is free. After that, a wig that is too large is a short piece of work in the Studio. One that is too small is harder, which is why the guidance above is to size up when you are between two.
