Shape Tailor
Four-way compression, mapped to your chest, waist and lower back — worn like a tank, gone the second it comes off.
- Holds your silhouette while it's on (four-way compression knit, panel-mapped to chest, waist and lower back)
- Disappears under a fitted shirt (flat-seam construction, no piping to show through)
- Holds its shape through a full day (recovers wash after wash, no sagging by afternoon)
- Fits your normal size (compression is built into the knit, not an undersized cut)
Sleeveless compression tank, scoop neck, flat-seam construction. Machine washable.
Compression zones are panel-mapped, not a uniform squeeze — denser knit across the chest, waist and lower back, standard four-way stretch everywhere else, so the tank moves with you instead of fighting you.
Order your usual tee size — S through 2XL, in Black or White. The compression comes from the knit itself, not from an undersized cut, so true-to-size fits true. Between two sizes? Size up for a more relaxed everyday feel, or size down for a snugger, more contoured hold.
Four-way stretch compression knit. Full fiber composition is confirmed and published once sourcing is finalized — see the garment care label for wash instructions in the meantime.
Free shipping on orders over $40. Orders ship within 24 hours. 30-day returns, no questions asked — we cover return shipping. Full policy on the Shipping & Returns page.

Engineering, not a gimmick
ShapeTailor is a men's compression tank built from a four-way stretch knit, with denser compression zones panelled across the chest, waist and lower back — the places a dress shirt or fitted tee actually shows shape. It contours your silhouette while it's on: shoulders back, waist held, nothing reads through a shirt.
Take it off, and it's just a tank again. No mechanism keeps working after it's in the laundry hamper — this is an effect you wear, not a treatment you undergo. Cut close enough to disappear under fitted clothing, finished with flat seams so nothing shows through a thin shirt.
Tap a zone to see what it's actually doing
A denser, wider knit band runs across the chest and upper back. It holds the shoulder line back, so a dress shirt sits square instead of pulling forward by midday.
The ribbed compression grid is where the tank does its most visible work — it pulls the waistline in and stops a fitted shirt from bunching at the hem.
A curved, mapped side seam follows your actual torso instead of a straight cut, so the tank contours instead of pinching under the arms.

Three steps. No routine to learn.
01 — Pull it on
Step in and pull to the shoulders like any tank. No clasps, no wrapping.
02 — Settle the hem
Adjust the hem at the waist so the compression zones sit where you actually hold weight.
03 — Wear it under anything
Under a tee, a dress shirt, a suit. Invisible under fabric, gone the second you take it off.
Real questions, answered straight.
No. The fabric is engineered thin enough to disappear under a fitted tee and a dress shirt. It reads as an undershirt, not a garment with structure.
No — and we won't tell you it does. ShapeTailor holds and contours your silhouette while it's on. Take it off, and you're back to how you started. That's the whole mechanism: compression while worn, nothing after.
Order your normal tee size. The compression is built into the knit, not into an undersized cut — sizing up or down won't change how it holds.
Yes — the same fabric that holds your silhouette under a shirt also supports through a workout. It's not a supplement or a training tool; it's a tank that happens to work in both settings.
