What to Put in Your Suit Pockets — From Pocket Square Folds to Practical Storage
7 ways to fold a pocket square plus a practical trouser pocket storage plan — no more bulging pockets
The most common mistake people make when wearing a suit is improper pocket use. Either they stuff the pockets full like they're going grocery shopping, or they leave the breast pocket empty — wasting the most ceremonial spot on the jacket. Every suit pocket has its own role. Use them right and your suit is both good-looking and functional. Use them wrong and you ruin it. This article covers both the breast pocket and trouser pockets, giving you the full picture.
The Breast Pocket: Decorative First, Functional Second
The left breast pocket of a suit jacket is designed not for carrying things, but for a pocket square. This tradition comes from European nobility — ladies would place scented handkerchiefs in a gentleman's coat pocket. Over time, the pocket square became a hallmark of a gentleman's outfit. The rule: only a pocket square goes in the breast pocket. No phone, pen, business cards, or lighter. Those will deform the pocket and ruin the jacket's line.
Many people think pocket squares are an old man's thing. But a well-chosen pocket square is the single best tool for taking an outfit from 60 to 80 points. It's the most understated "I care about details" accessory. A white linen pocket square works with nearly every suit and shirt color.
7 Classic Pocket Square Folds
1. Presidential Fold: The simplest and cleanest. Fold the square into a wide strip, then fold the ends inward to form a rectangle. Insert with about 1 cm showing. Clean, crisp, perfect for formal suits and tuxedos.
2. Triangle Fold: The most common. Fold diagonally into a triangle, fold the base corners inward behind. Great for business meetings and daily office wear.
3. Crown Fold (Four-Point): Fold each corner toward the center to create a raised multi-point shape. Best for casual or semi-formal settings with patterned or light suits.
4. Two-Point Fold: Fold diagonally, then fold two base corners upward to create two peaks. Adjust height difference for asymmetry.
5. Puff Fold: Pinch the center, pull corners inward to form a fluffy ball. The most casual yet elegant. Best with linen suits.
6. Three-Point Fold: Fold into a rectangle, then narrower, fold both ends up to form three peaks. Exquisitely polished for formal wear.
7. Winged Puff: Fold into a rectangle, pinch center, press an indent before inserting. Like an open fan. Niche style for slim-fit suits.
General rule: the more formal the suit, the simpler the fold.
Pocket Square and Tie Pairing
Core principle: don't match exactly — coordinate. If your tie is solid navy, use white. If your tie has stripes, pick a solid square in an accent color. One busy, one simple. Never buy "matching sets" — identical pattern and material was fashionable 20 years ago. Now it's tacky.
Other Pockets
A suit jacket has two outer pockets and two inner pockets. Outer pockets: don't put heavy items in them. A coin is okay, but a phone or keys will deform the jacket. Inner pockets are the only place for items. Left inner: business card case or phone. Right inner: pen or small documents. Even inner pockets shouldn't carry anything too thick.
Trouser pockets: Don't stuff front pockets with keys, phone, or wallet. It creates bulges and ruins the drape. Back pockets can hold a handkerchief or slim wallet — but a thick wallet creates a visible bump when seated.
Where to Put Your Wallet and Phone
Standard answer: inner pockets. Left inner for phone, right inner for wallet. But inner pockets have thickness limits. When wearing a suit, use a slim cardholder — just 2-3 cards and minimal cash. Remove unused membership cards.
Better solution: use a leather folio or briefcase. Keep everything in the bag — suit pockets stay empty and clean. This is the most "elegant" way, but you need to be comfortable carrying a bag.
Emergency Carry Items
A few small items worth keeping in your briefcase or inner pocket: a portable fabric shaver (elbows and back of suits pill over time), a stain removal pen (for accidental drops during meals), a shoeshine cloth, and a foldable comb. Your suit doesn't need to be the most expensive — as long as it's clean and tidy, it feels intentional.
Pocket Square Sizing and Material
Standard pocket square size: 30-40 cm square. 30 cm works with slim-fit modern suits but limits fold options. 40 cm fits traditional cuts but may bulge out of a fitted pocket. The most recommended: 35x35 cm — versatile for all fold types.
Materials: White linen is the most classic and versatile. Linen's natural imperfection adds elegance. Silk has more sheen and vivid colors — great for evening occasions. Cotton is simpler and more affordable for daily office wear. Blends combine benefits but lack the feel of natural materials.
Final tip: whatever fold you use, gently "adjust" the square with your fingertips after inserting — make it look natural, not stiff. Don't jam it in tightly. A slight irregularity adds character. That's the philosophy of the pocket square — it's the one element in your entire outfit allowed to be imperfect, breaking the suit's formality.
