Quick answer: Plus fours are full-cut sporting trousers that end in a band below the knee, with extra length that blouses over the band, and breeks are the slimmer shooting cousin with less overhang. Write the style, the fullness, the band closure and how far the overhang drops, then check the sample while the wearer crouches, kneels and swings. Shi Yuan (Suit Factory) takes MTM from 1 and bulk from 50 per style for overseas tailor shops, MTM boutiques and private-label brands, not retail — send the style word and a side photo of a reference pair on WhatsApp.
A country outfitter wants a tweed shooting suit with breeks. A golf club shop wants plus fours in a heritage check for members. Both orders look like a pair of trousers that stop at the knee. Both go wrong in the same place: the band is too tight when the wearer bends, or the overhang sits in a lump on one side. The riding cousin of this garment has its own brief in the jodhpurs and breeches brief.
What are plus fours, plus twos and breeks?
All three are below-knee sporting trousers with a band that closes under the knee, worn with long socks. The names describe how much extra length hangs over the band. Plus fours have the most overhang and the fullest leg, the classic golf look. Plus twos are shorter and neater, with less blousing. Breeks are the slimmest, cut close with a modest overhang, usual for shooting and walking where a full leg catches on gorse and gates.
The names are not a measurement system. One shop's plus twos are another's breeks. Write the look you want in words and send a side photo; the factory reads the photo together with the word.
Style decision table
| Style | Leg fullness | Overhang over band | Typical use | Brief risk if vague |
|---|---|---|---|---|
| Plus fours | Full through thigh and knee | Generous, blouses well over | Golf, heritage dress | Sample arrives looking like breeks |
| Plus twos | Moderate | Short, neat drop | Golf, smarter country wear | Overhang lands unevenly |
| Breeks | Close-cut | Modest | Shooting, walking | Too tight to kneel or climb |
| Breeches (riding) | Shaped for the saddle | None or minimal | Riding | Wrong garment — use the riding brief |
Same table as a list
- Plus fours: full through thigh and knee, generous overhang — golf and heritage dress; risk: the sample arrives looking like breeks.
- Plus twos: moderate fullness, short neat drop — golf and smarter country wear; risk: the overhang lands unevenly.
- Breeks: close-cut, modest overhang — shooting and walking; risk: too tight to kneel or climb.
- Riding breeches: shaped for the saddle, little or no overhang — riding; use the riding brief instead.
The knee band and closure
The band is where most complaints start. Choose the closure and write it: a strap and buckle, a button tab, or a buttoned band with a side opening. Say whether the band sits just below the knee or a little lower. Then say whether the band should allow a sock turned over it or sit over the sock. A band measured with the client standing will feel tight when he crouches, so take the below-knee measurement and tell the factory the main activity: golf, shooting, walking.
Write the side opening length in words, such as "opening to clear the calf", rather than leaving it to a default from another garment.
Cloth
Tweed is the usual choice: it is firm, warm and hides mud. Heavier tweeds hold the overhang in a crisp fold; softer tweeds collapse into a softer blouse. Moleskin and cavalry-twill style cloths suit breeks for drier days. Tweed's handling on the cutting table and at the sample is covered in the tweed cloth brief. If the trousers match a jacket, write that both come from the same cloth reference so the colour matches.

A worked note
"Client ref A-12. Shooting breeks in the jacket's tweed, same cloth reference. Close-cut, modest overhang. Buttoned band with buckle strap, just below the knee, over the sock. Side adjusters. Two hip pockets with button flaps. Main use: shooting, kneeling often. Side photo of reference pair attached."
At the sample
- Stand: the overhang should fall evenly on both legs.
- Crouch: the band should not bite and the seat should not strain.
- Kneel on one knee: the knee should have room; nothing should pull at the band.
- Golf clients: take a slow swing and watch the band and the overhang.
- Check the band closure opens and closes without fighting the cloth.
The sporting jacket that often goes with these trousers is a separate brief; see the action-back jacket brief.
Private-label notes
A brand that sells plus fours in a size run needs one more decision: how the band is sized. A fixed band suits a narrow size range; an adjustable strap covers more calves. Write the band rule into the house spec so each size is not argued separately. Seal the overhang look on the base size; a sealed side photo prevents drift between sizes.

FAQ
What are Shi Yuan's order tracks and clocks?

WhatsApp +65 8013 8838.
Do plus fours need a different measurement from normal trousers? Yes. Add the below-knee measurement where the band sits, and the calf if the client is muscular. The outside leg is taken to the band, not to the floor.
Can plus fours be made as part of a three-piece tweed suit? Yes, if the order names the same cloth reference for jacket, waistcoat and trousers, and each garment has its own lines.
