Buying a jacket is easy. Knowing what to wear it with on a Tuesday at 7:40 a.m. is the hard part. This guide to LitBuy Spreadsheet Jackets skips the history lesson and hands you five outfit formulas you can copy, plus a simple way to size a jacket so a hoodie actually fits under it. Browse the jackets category in one tab and keep this page open in the other.
Five Jacket Outfit Formulas by Occasion
Each formula lists the slots from the outside in: jacket, layer, bottom, shoe. Swap the colors and you get a new outfit without new thinking.
1. The Commute
Formula: clean shell or coach jacket + plain crewneck tee + straight-leg pants + low-profile sneakers. The goal is zero friction. Neutral top, neutral bottom, and let the jacket carry one color.
2. The Weekend
Formula: relaxed overshirt or trucker-style jacket + graphic tee or hoodie + loose pants + chunky sneakers. This is where you can be louder. If the tee has a print, keep the jacket plain, and the other way round. One star per outfit.
3. The Travel Day
Formula: packable light jacket + zip hoodie + soft tapered pants + slip-friendly shoes. Airports and train stations swing between freezing and stuffy, so you want two removable layers.
4. The Night Out
Formula: cropped or structured jacket + fitted dark tee + dark straight or slim pants + clean leather-look shoes. Darker palette, sharper lines. A shorter jacket shows more of the leg and reads taller and tidier in dim light.
5. The Rainy Day
Formula: hooded water-resistant shell + fleece or light knit + quick-dry pants + shoes you will not cry over. Check that the hood has a brim or adjuster, and that the hem covers your waistband when you lift your arms. Wet lower back is the worst.
Sizing a Jacket for a Layer Underneath
Most size charts assume a T-shirt underneath. If you plan to wear a hoodie under it, measure like this:
- Put on your thickest hoodie, the one you would actually wear under the jacket.
- Measure your chest around the fullest part, over the hoodie, tape snug but not tight.
- Measure sleeve length from the center back of the neck, over the shoulder, down to the wrist bone, arm slightly bent.
- Compare to the listed garment measurements, not the body chart.
Rule of thumb: the jacket chest (pit to pit doubled) should be roughly 8 to 12 cm larger than your over-hoodie chest for a comfortable fit. Under 6 cm and you will feel like a stuffed dumpling.
| What you wear underneath | Size decision |
|---|---|
| T-shirt only | True to size |
| Thin knit or long sleeve | True to size, check sleeve |
| Midweight hoodie | Size up one |
| Heavy fleece hoodie | Size up one, confirm chest by tape |
Worked example: your chest over a hoodie measures 104 cm. You want 112 to 116 cm of jacket. A listing showing 57 cm pit to pit gives 114 cm, which lands in the sweet spot. Sleeve over the hoodie measures 84 cm from the neck, so look for 84 to 86 cm. If you plan to size up for an oversized look, read the hoodie guide first so both layers agree.
Building the Rest of the Formula
The bottom half matters as much as the jacket. Matching leg width to jacket length is covered in the pants guide, and if you want to see which outerwear styles are trending this year, the 2026 spreadsheet roundup has you covered. The full catalog lives on the LitBuy Spreadsheet.
FAQ
Should I size up for an oversized look?
Only if the shoulders are designed to drop. Sizing up a fitted jacket just makes the sleeves long. Check the shoulder measurement first.
Which formula works for most days?
The commute formula. Neutral, quiet and easy to dress up or down with shoes alone.
Pick a formula, measure once with your hoodie on, and you will never stand frozen at the closet again. Head back to the LitBuy Spreadsheet homepage to start browsing, or jump to the full category list.
