A good suit comes down to four checkable things: construction behind the fabric, how shoulders and collar sit, clean finishing, and enough interior fabric to let a tailor adjust it.
Run a thumb along the fabric under the lowest buttonhole. Two shifting layers mean a floating canvas; one rigid bonded slab means glue holding the jacket together, and glue eventually lets go. That pinch tells you more about how a suit will look in three years than the price tag or the “Super 150s” label.
What Construction Is Inside The Jacket?
- Full canvas: a floating wool, horsehair, or animal-hair layer runs through chest, lapels, and lower front, stitched rather than glued. It drapes naturally and molds to the wearer.
- Half canvas: canvas supports chest and lapels, lower front built separately. The middle ground most buyers land on.
- Fused: synthetic interlining heat-bonded to the shell. Cheapest, stiffer, less breathable, prone to bubbling as adhesive ages.
“Canvas” doesn’t automatically mean full canvas — half-canvas jackets have fused sections. A canvassed lapel rolls softly toward the chest; a fused one lies flat or creases sharper.
How Should A Suit Actually Fit?
Fit beats fabric, construction, and brand, because almost nothing about a bad fit can be fixed later.
- Shoulder seam ends at the edge of your shoulder bone — not past it, not inboard.
- Buttoned, a flat hand slides between chest and jacket without strain. A fist means too much room; no room means too tight.
- The jacket covers your seat; fingers curl around the hem with arms relaxed.
- About ¼–½ inch of shirt cuff shows below the sleeve.
- Collar lies flat against your neck with no gap.
- Trousers fall cleanly to the shoe with one moderate break.
Shoulders, collar, and jacket length are the hard ones; sleeves, trouser length, and waist are easy — that’s where your tailoring budget belongs. For what to spend, our roundup of tested bargain suits that still tailor well shows what the low end can deliver.
Which Finishing Details Give A Suit Away?
Seams should be flat, clean, and generous enough to let a tailor let the garment out later — that spare fabric is called inlay. The lining should sit smoothly with no pulling or twisting. Buttonholes even and securely finished; buttons firmly attached. Working sleeve buttons and hand-finishing signal extra workmanship but never compensate for poor fit, weak fabric, or glued fronts.
Ball up a fabric section for three seconds and release: good wool springs back with few creases. Weight matters — roughly 9 to 11 ounces drapes well and holds a press, though the right number depends on climate and wear frequency. Judge blends on how they feel, breathe, and wear, not fiber percentage alone.
Check stripes and checks at seams, pockets, and shoulders. Misaligned patterns point to rushed cutting. Puckering, loose threads, distorted pockets, uneven lapels, and visible rippling are all reasons to walk.
What Should You Pay, And In What Order Do You Decide?
Price bands are broad categories, not guarantees, but MenswearHouse’s buying guide puts them in useful terms.
| Price Range | What It Typically Buys | Best For |
|---|---|---|
| $200–$400 | Wool blends or polyester-wool, fused fronts, basic linings | Starter, event, or backup suits |
| $400–$800 | Higher wool content, better drape, Bemberg linings, often half canvas | Regular wear and office rotation |
| $800 and up | Finer wool, full canvas, premium linings, hand-finished details | Frequent wear and long-term investment |
A well-fitting $500 suit beats an ill-fitting $1,200 one every time. Brand names and sale prices can’t rescue a jacket needing shoulder reconstruction.
Decide the use first — office, interview, wedding, travel, warm weather, or heavy rotation. Match fabric weight to climate and wear frequency. Pinch beneath the lowest buttonhole to check construction. Try the jacket on over the shirt and shoes you’d actually wear. Evaluate in order: shoulders, collar, chest, jacket length, sleeves, trouser waist, seat, break. Inspect seams, pattern matching, lining, buttonholes. Confirm return and alteration policies before paying.
The most common trap is chasing a high Super number while ignoring construction, fit, and durability. The second is buying too tight, even though shoulders and length can’t be repaired.
Common Questions
Is a fused jacket ever worth buying?
Yes, at the entry level. Fused construction is the least expensive way to build a jacket and works fine for occasional wear, travel, or backup. Expect it stiffer and less breathable than canvas, and watch for bubbling near the buttonholes over time. If a front starts to separate, the jacket is done.
Can a tailor fix shoulders that don’t fit?
Rarely at reasonable cost. Narrowing or widening shoulders and rebuilding collar fit means taking the jacket apart, usually close to the price of the suit itself. That’s why shoulders, collar, and jacket length should be judged at purchase. Sleeves, trouser length, and waist are simple and inexpensive by comparison.
Does a higher Super number mean a better suit?
No, and it can work against you. Super describes fiber fineness, not weave quality, finishing, or durability. Very fine wool wears faster, wrinkles more easily under daily use, and needs gentler care. For weekly wear, a solid mid-weight wool with sound construction serves you better than fragile high-Super cloth.
