Men’s Measurement Guide
Follow these simple steps to ensure your custom garment fits you perfectly. All you need is a flexible measuring tape.
How to Measure Your Chest
- Stand up straight with your arms relaxed at your sides.
- Wrap the measuring tape around the fullest part of your chest, typically right under your armpits.
- Keep the tape parallel to the floor.
- The tape should be snug against your body but not tight enough to restrict breathing.
- Read the measurement in the mirror or have someone help you.
How to Measure Your Waist
- Identify the exact position where you normally wear the waistband of your trousers. This is typically at or just below your navel (belly button).
- Wrap the measuring tape around your body at that specific point. Ensure the tape is level and parallel to the floor.
- Stand in a relaxed, natural posture. Do not suck in your stomach or push it out.
- The tape should be snug, but not tight. For a comfortable fit, you should be able to place one finger between the tape and your body.

Description
The navy flannel suit is a cornerstone of the sophisticated masculine wardrobe, a versatile garment that bridges the gap between formal and casual with unparalleled elegance. Our interpretation is commissioned in a fine Super 120s’ wool flannel—a cloth with a soft, brushed hand and a distinctly supple drape, offering the visual depth of traditional flannel without the weight.
The Architecture of the Navy Flannel Suit
The jacket is built upon a full, hand-basted canvas front, an unseen architecture that allows the garment to mold to the wearer over time. The trousers are designed with a full skirt-lining in the waistband for a clean, comfortable drape. Every detail, from the hand-carved horn buttons to the final silhouette you define, is executed with precision.
A Personal Commission
The creation of your suit is a collaborative process. Through our customizer, you will define the final silhouette—from a classic tailored fit to a more relaxed interpretation—and specify personal details, such as the inclusion of a ticket pocket. Accommodations, such as a fully extended trouser lining, are naturally part of our bespoke service.
The Bespoke Promise: Your Fitting Canvas
A garment of such foundational importance demands an unimpeachable fit. Your commission therefore begins with a preliminary fitting suit—a toile—crafted to your initial specifications. This critical step allows for the meticulous refinement of the suit’s balance and line, ensuring the final flannel piece is achieved with absolute precision. The fitting canvas is, of course, yours to retain.
Dry-clean.

Really Beautiful Fabric
This is my fifth suit from Baron Boutique and it is beautifully made as I expected. I’ve moved to a cold climate where I can wear wool comfortably. I was looking for a wool that is soft like flannel, but not so heavy. This fabric is as described, lighter than traditional flannel, but soft with a great hand. What I like about Baron is that they are flexible and accurate in customizing the suit. For my suite style, I prefer 3/4 length Nehru jackets. I find a suit with the fabric and trousers that I like and ask for the jacket the way I want it. Besides the suit the best part of this transaction was that the suit was made and delivered in under two weeks. More important that the time is that I was told when to expect the suit when the order was confirmed and I received it as promised.
