What is the exact fiber composition of the stretch Marzotto wool? For example, what percentage of wool and what type of stretch fiber (e.g., elastane)?

The stretch Marzotto wool is 98% wool and 2% elastane, as confirmed by the fabric mill's specification used in our Marzotto tuxedo suits. This blend provides the stretch and recovery typical of Marzotto's woven wool fabrics.

Are the buttoned piped back pockets functional or decorative?

Yes, the buttoned piped back pockets are functional – they feature a button closure for secure storage, suitable for small items like a wallet or phone. This is a standard design in tailored trousers.

Is the satiny band made of actual satin or a synthetic substitute, and is it sewn onto the pant or part of the weave?

The satiny band is a separate strip of satin fabric sewn onto the outer side seam of the pant, not part of the weave. It matches the satin lapel facing of the matching jacket. While we cannot confirm the exact fiber content of the satin from the product data, it typically is a polyester or blended satin for durability and sheen.

Does the London fit (slim straight) run true to size compared to other brands? For a size 32 waist, what is the exact waist measurement?

The London fit runs true to size – a size 32 waist measures approximately 32 inches. The slim straight cut is consistent with standard sizing for this style. For the best fit, we recommend referring to our size chart or visiting a store for a personalized fitting.

Deep Research

Unfinished hem and free hemming service

The hemming appointment lets the tailor pin the length while you are in your dress shoes, so you can choose the exact trouser break — from a deep crease onto the vamp to a clean, no-break line above the shoe — which dramatically refines the slim-straight silhouette.
An unfinished hem on formal trousers is a deliberate signal that the garment is built to be tailored to the wearer's precise measurements — unlike pre-hemmed alternatives that often need shortening anyway but retain a factory-finished edge that betrays a generic starting length.
Simons includes free hemming with the purchase, which means the $250 CAD price covers the tailoring normally charged $20–$30 by an independent shop, delivering a custom-length pant without a separate errand or additional bill.
Because the satiny stripe runs the side seam, an expert hem must reattach the band so the vertical line stays uninterrupted; having the work done at Simons means the tailor is familiar with the garment's construction, reducing the chance of a misaligned detail that can disrupt the tuxedo's formal stripe.
