Every Adam & Westcott cardigan carries S through XL, but only two of the twenty four go past 2XL.

Buy the same letter you already wear in a shirt. All 24 active Adam & Westcott cardigans carry S, M, L and XL, 22 add 2XL, 14 open at XS, and only two continue past 2XL. These are knits with give, so the size that fits your shirt almost always fits the cardigan over it.

What sizes do Adam & Westcott cardigans come in?
The range runs XS to 7XL on paper, but no single cardigan covers that span. Here is how often each size appears across the 24 active listings.
| Size | Cardigans carrying it | What that means for you |
|---|---|---|
| XS | 14 of 24 | Just over half the range, mostly newer autumn knits |
| S, M, L, XL | 24 of 24 | Every cardigan we sell, so style is your only call |
| 2XL | 22 of 24 | Nearly all. The two exceptions stop at XL |
| 3XL | 1 of 24 | One listing only, so check before buying |
| 4XL and 5XL | 2 of 24 | Two listings carry both |
| 6XL and 7XL | 1 of 24 | The Jacquard Knit Button Cardigan alone |
Should I size up a cardigan for layering?
Usually no. Stay at your shirt letter, because the shirt underneath varies far more than the cardigan. At L, the chest measurement printed on our shirts spans 8.6 inches by cut, and that gap decides whether a cardigan feels close or roomy.
| Shirt worn underneath | Chest at L | Cardigan advice |
|---|---|---|
 Modern Workwear Denim Shirt |
40.2 in | Trimmest. Stay at your usual letter |
 CoreOps Button-Up Shirt |
45.7 in | True to size. Shirt letter is cardigan letter |
 Linen Chest Pocket Shirt |
48.8 in | Oversized. One size up is sensible |
Our cardigans do not publish a chest chart, so the shirt measurement is the honest reference point.
Which cardigans go past 2XL?
Two, and they behave differently. Above 2XL, these are your only options.
Ten consecutive sizes, S through 7XL, with a turn down collar, button front and two front pockets. Nothing else in the range comes close.
Runs S, M, L, XL, 2XL, then jumps to 4XL and 5XL. There is no 3XL here, so a 3XL buyer needs the Jacquard Knit Button Cardigan. Ribbed trim holds its shape.
The two that stop at XL matter for the opposite reason. The 
Merino Wool Cardigan at $69.98 runs S to XL only, and is the one listing stating its fibre content in full at 100% merino wool. The 
Tipped Zip Knit Cardigan at $62.99 runs XS to XL in a soft cotton blend knit.
Which cardigans run roomy and which run close?
Nine of the 24 state a fit in their own copy, and those are where your letter shifts. Four say relaxed, three say loose, three say roomy.
-
V-Neck Knit Cardigan $55.98, the only listing described as both oversized and loose. Size down for a close fit. -
Loose Fit Textured Cardigan $47.98, the lowest price in the range, loose fit by name. -
Stand Collar Cardigan $59.98, relaxed fit, XS to 2XL. Usual letter is right. -
Jacquard Knit Cardigan $55.98, the only cardigan in our last 14 days of top sellers. S to 2XL, open button front.
What does a cardigan cost?
They run $47.98 to $69.99. Eight of the 24 sit under $50, ten between $50 and $59.99, and six at $60 or above. The widest size run, the Jacquard Knit Button Cardigan at $49.98, sits in the lowest band, so a bigger size costs no more.
Cardigan sizing FAQ
What size cardigan should I buy if I wear a large shirt?
Buy L. All 24 Adam & Westcott cardigans carry L, and the knit has enough give to sit over a shirt at the same letter.
Do Adam & Westcott cardigans run small?
No. They are cut to layer, so your shirt letter is the starting point. Only an oversized shirt underneath, like the Linen Chest Pocket Shirt at 48.8 inches at L, makes a size up worth it.
Is there a 3XL cardigan?
Yes, one. The Jacquard Knit Button Cardigan at $49.98 is the only listing carrying 3XL, and it runs to 7XL.
Which cardigan has the most sizes?
The Jacquard Knit Button Cardigan, with ten sizes from S to 7XL. The next widest is the Clean Button Cardigan with seven.
Do cardigans come with a chest measurement?
No. None of the 24 publishes an inch chart, so size from the shirt underneath and the fit each listing states.
