Size Guide

Everything below is the garment measured flat, not your body. Chest is the full width from armpit seam to armpit seam; length runs from the highest shoulder point down to the hem. Fastest way to get it right: take a jersey that fits you well, measure it the same way, and match the numbers.

Men's / Unisex Big & Tall Authentic (numbered) Youth Preschool / Toddler Women's
Diagram: measure straight across the chest from armpit seam to armpit seam, and from the top of the shoulder down to the hem
ChestLay the jersey flat and measure straight across, from one armpit seam to the other. That full width is the number in the chart - so a chart reading of 44 in means the shirt measures 44 in across, not a 44 in body.
LengthFrom the highest point of the shoulder straight down to the bottom hem, with the jersey laid flat and smoothed out.

Men's / Unisex Jerseys

Authentic - Numbered Sizing

36 - 64

Some Authentic styles are sold by number instead of letter. The number is the chest width in inches - so a size 48 measures 48 in across. Use the letter column to translate your usual size.

Number Equals Chest (in) Length (in) Chest (cm) Length (cm)
36 XS 36 29 91 74
40 S 40 30 102 76

Youth Jerseys

M 9-10 yrs 30-32 23 76-81 58

XL 13-14 yrs 34-36 26 86-91 66

Preschool & Toddler

2T - 7 / 12M - 24M

Worded by age rather than letter on purpose - this is the range where children grow fastest, so measure a shirt that fits today and match the chest.

Size Age Chest (in) Length (in) Chest (cm) Length (cm)

Women's Jerseys

01
Cut for comfort

Basketball jerseys are meant to hang loose. If you want a regular, closer fit, order one size below your usual.

02
Between sizes?

Go up. The extra room is how the cut is designed to be worn, and it layers over a hoodie in winter without pulling.

03
Compare, don't guess

Match the numbers to a shirt you already own rather than to your body. Printed names and numbers on the back do not change the fit.

Numbers are taken flat and can vary by roughly 1 in / 2 cm between styles, and Youth overlaps Preschool at age 7 - in that case Youth S is the slightly longer of the two. Still unsure? Contact us with your height, usual size and the jersey you are looking at, and we will tell you which one to take.

Description

Boston Celtics White, Jayson Tatum’s number on the back — built for nights that run long.

Think of it as the shirt that lives near the door during the season — easy to grab, easy to wear, easy to wash and put straight back on. It is the Boston Celtics jersey in White — and it is unmistakably Jayson Tatum’s. The lettering is sealed on rather than stitched in, so the inside stays smooth against the skin.

It is knitted, not woven, and the wicking finish is what keeps it comfortable late in the game. Inside the neck there is taping rather than a tag, so the shirt stays comfortable as long as you keep it on. It pairs with jeans, shorts or whatever is clean, which is most of why it gets worn weekly. Nothing about it is precious — which is exactly why it ends up worn the most. It packs down small, which makes it an easy one to take to an away game.

Why it works

  • True to the team lookThe White and the marks follow the Boston Celtics palette rather than approximating it.
  • Pairs with everythingJeans, shorts, a jacket in November — the White is easy to build around.

  • Layer-friendlyRelaxed enough to sit over a tee without bulking up at the shoulders.

Points to note

How does it arrive?

Pressed, folded and ready to wear — there is no assembly or first-wash ritual.

Is the fabric breathable enough for summer?

Yes — the recycled polyester knit with a wicking finish is built for warm evenings.

What colour is it exactly?

This listing is the White colourway — other colourways are linked from the same product page.

Is it comfortable straight from the bag?

Yes. There is no breaking-in period and no label in the neck to scratch.
