How to Choose Hoodie Size Online: Oversized or Regular

Buying a hoodie online means choosing a size without trying it on, and a hoodie that is meant to be roomy makes that harder: too small and it is just a tight hoodie, too big and it swallows you. This guide shows a simple method to choose your size from real measurements, using the OKU hoodies and sweatshirt as the worked example. Nothing here relies on guesswork: every number comes from the OKU size guide.

Step 1: know that the cut runs large

The OKU hoodies and sweatshirts are cut on Stanley/Stella blanks. The maker's sheet says this model runs large in Europe: between two sizes, take the smaller one. That sentence matters more than any chart, so keep it in mind for every step below. If you normally wear an M and you want a relaxed shape, M is already generous.

Step 2: measure a hoodie you already own

Charts in centimetres are only useful if you compare them with something real. Take the hoodie you like most, lay it flat on a bed or a table, smooth it out, and measure:

• Width: straight across, from one armpit to the other.
• Length: from the top of the shoulder, next to the collar, to the bottom hem.
• Sleeve: from the shoulder seam to the end of the cuff.

Write the three numbers down. They are measured exactly the way the size guide measures its garments (laid flat, width from armpit to armpit).

Step 3: compare with the OKU hoodie table

The table below applies to the OKU Embroidered Hoodie (€85) and the OKU 奥 Hoodie (€79). Measurements are in cm, garment laid flat.

Size	Width	Length	Sleeve
S	50	68	63.5
M	54	70	65.5
L	58	72	67.5
XL	63	75	68
2XL	68	77.5	68.5

The size guide notes that a piece may vary by up to 5 cm, so treat the numbers as a guide, not a promise to the millimetre. Because the width is measured flat, doubling it gives the full circumference: for example, a flat width of 54 cm (size M) is a garment circumference of 108 cm. That is simple arithmetic, not a body measurement.

Step 4: decide how you want it to fit

Regular fit

Pick the size whose width is close to your reference hoodie. Since the cut already runs large, this gives a comfortable, slightly relaxed hoodie rather than a fitted one.

Oversized fit

For a drop-shoulder, layered look, choose a width 4 to 5 cm larger than your reference hoodie. Each step in the table adds 4 to 5 cm of width (50, 54, 58, 63, 68), so in practice that means going up one size from the regular choice. Note that the length also grows by only 2 to 3 cm per size, so an oversized hoodie ends up wider rather than much longer.

Closer fit

If you want it nearer the body, go one size down from your reference. This works because the cut runs large.

Hoodie, sweatshirt or tee: sizes are not identical

Do not assume that your hoodie size transfers to every piece. Here are the real differences:

• The OKU Enso Sweatshirt (€69, crew neck, relaxed fit) has the same widths as the hoodie, with a slightly longer body (68.5 to 78.5 cm). It also runs large.
• The OKU Embroidered T-Shirt (€45, regular fit) runs large too, so between two sizes take the smaller one.
• The printed tees (such as the OKU 奥 T-Shirt, €45, medium fit) come from XS to 2XL and the size guide lists the chest range for each: S is 78.5 to 86.5 cm, M is 89 to 96.5 cm, L is 99 to 104 cm.

If you are layering a tee under a hoodie, size each piece on its own measurements rather than copying your size across.

Caps, beanies and socks

These are simpler. The OKU Hanko Embroidered Cap is one size with an adjustable strap, for a head circumference of 52 to 62 cm. The beanie is one size and stretchy, for 42 to 58 cm. The OKU Leaf Socks come in M (EU shoe size 38 to 41), L (42 to 45) and XL (46 to 49).
