Product Insights
Le 31's Stretch Tuxedo Vest is a formal black-tie piece built from Marzotto's stretch wool weave (98% wool, 2% elastane) sourced from the Valdagno mill in Italy, though assembly is 'Made in Europe' rather than Italy. The fabric is engineered to recover shape after movement, resist pilling, and wick away humidity while blocking outside moisture, making it a midweight all-season formal layer. Its jetted piped side pockets (without flaps) are a mark of dinner-jacket formality, and the satin back is intended to lie flat when worn without a jacket; however, those two pockets are the only storage (no interior pockets), and the only fit adjustment is a waist strap, so sizing must be based on chest and shoulders. Offered only in even sizes 36–48, all at CAD 250, odd-size wearers choose the nearest even, and product photography references a size 40 with other sizes extrapolated. As Simons' in-house formalwear label, the vest pairs with the matching Le 31 Stretch Tuxedo Jacket and trousers in the same Marzotto fabric, and strict black-tie protocol dictates wearing it with that jacket rather than alone.
Verified claims
- Stretch recovery
- Stretch Marzotto wool bends for comfort and recovers to prevent bagging.
- Breathability
- Wool expels body humidity and blocks outside moisture, keeping the torso dry.
- Pilling resistance
- Fabric is anti-pilling, resisting fuzzballs from friction.
- Fabric provenance
- Marzotto Tessuti of Valdagno, Italy weaves the shell; the label says Made in Europe, not Made in Italy.
- Fabric performance
- Marzotto stretch wool is engineered to recover shape and buffer humidity for all-season wear.
- Pocket style
- Tailoring sources rate flat piped front pockets among the most formal pocket styles, expected on dinner jackets.
- Piped pockets
- Jetted piped pockets with no flaps identify this as a true black-tie vest.
- Pocket storage
- All storage is the two low piped front slits; there is no interior pocket.
- Satin back
- Satiny back lies flat through the waist and is accepted when the vest is worn without a jacket.
- Back adjustment
- The adjustable waist strap with satin back enables a custom fit without gapping, but only at the waist; choose the size by chest and shoulders.
- Brand provenance
- Le 31 is Simons' in-house formalwear label — Simons was founded in Quebec City in 1840.
- Material
- Marzotto front: 98% wool, 2% elastane, woven by the Valdagno mill; back lining is 100% polyester.
- Price rationale
- At 250 CAD, a Le 31 house label carries no external designer license fee.
- Set coordination
- Matching jacket 16858-226464 shares the same Marzotto wool, pairing a satin shawl collar with the vest's satin back.
- Pocket design
- Piped front pockets are functional jetted openings that keep the formal front flat.
- Size range
- Sizes run 36-48 in even numbers only; all seven cost 250 CAD and are in stock.
- Black-tie protocol
- Under strict black-tie, wear it with the matching Stretch Tuxedo Jacket, not alone.
- Fabric weight
- A midweight year-round Marzotto cloth, not an ultra-light summer weave
- Seasonality
- Wool wicks moisture and buffers humidity for all-season formal wear
- Matching fabric
- Matching jacket and trousers share the same stretch Marzotto wool cloth
- Sizing
- Only even sizes 36-48 are offered; buyers who normally take an odd suit size must choose the adjacent smaller or larger even size.
- Size pricing
- Every size 36-48 costs 250 CAD; no size carries an oversize markup.
- Photo reference
- Product photos show a size 40 vest; other sizes are extrapolated from it.
- Shade consistency
- Black shade and stretch Marzotto fabric carry through the matching Simons jacket and trousers as one tuxedo set.
- Fabric composition
- The vest is made from 98% wool and 2% elastane stretch Marzotto wool, with a polyester lining.
- Satin back construction
- The satiny back is a full fabric panel, not a backless style, with an added waist-cinch strap at the lower back and no open gap through the middle.
- Care
- Dry clean only is recommended to preserve the stretch Marzotto wool's shape and finish; spot cleaning with a damp cloth may work for minor marks, but machine washing or hand washing can damage the wool and stretch fibers.
- Sizing guidance
- The Stockholm fit is intended to be worn close to the body; buyers with a proportional build should stick with their usual US suit jacket size, while those who prefer extra room or have a larger chest may want to size up.
