PDF SEWING PATTERN | September Extended Coat | Merchant & Mills
Skill Level: Intermediate
Sizes: UK 18–28
Language: English only
The September Extended Coat PDF sewing pattern by Merchant & Mills is an oversized overcoat that blends the relaxed feel of a duster with timeless workwear styling. Designed specifically for the extended size range, it can be sewn lined or unlined to suit every season.
Choose heavyweight linen for an elegant everyday coat, Dry Oilskin for wet-weather protection, wool for winter warmth or canvas and denim for a durable utility-inspired jacket. Its generous oversized silhouette makes layering effortless while maintaining a modern, relaxed look.
The September Extended Coat is intentionally oversized. We recommend checking the finished garment measurements to choose the amount of ease that best suits your personal style.
Looking for smaller sizes? The September Coat PDF Sewing Pattern is also available in UK sizes 6–18. Shop the standard size range here.
All seam allowances are 1.5 cm (⅝") unless otherwise stated and are included in the pattern.

Shipping Policy
We are committed to providing reliable nationwide delivery using trusted shipping partners.
Québec and Ontario
We’ve recently updated our shipping options to give you more flexibility and competitive rates. At checkout, you can now choose from multiple carriers — including Canada Post, ICS Courrier, Canpar, Purolator, FedEx, UPS, and more.
Shipping fees are automatically calculated based on the weight of your order, with several delivery options and prices available.
If a carrier does not service your address, we may need to use an alternative option, which could incur additional charges, particularly for P.O. box addresses.
For remote or rural areas where delivery costs are higher, additional fees may apply. In these cases, we will provide proof of the shipping costs to ensure transparency.
Other Provinces in Canada, USA, and International Shipping
For customers in other Canadian provinces, the USA, or internationally, we offer a range of shipping options through various carriers. The customer is responsible for selecting their preferred shipping method at checkout.
Please note that our system provides an estimated shipping cost at checkout, which may not always reflect the actual shipping charges.
In cases of oversized orders, shipments to rural or remote areas, or delivery to P.O. boxes, the final shipping cost may differ. If this occurs, we will contact you directly with the updated shipping cost, which will be the responsibility of the customer.
Import Duties & Customs Fees (USA & International Orders)
All orders shipped outside of Canada — including to the United States — may be subject to import duties, customs fees, taxes and other charges assessed by the destination country’s customs authorities. These charges are not included in the item price or shipping cost and are the sole responsibility of the customer.
Customers agree to pay any duties, taxes, fees, or charges required by the destination country in order for customs to release the package. Failure to pay such charges may result in your order being returned or abandoned by the carrier, and no refunds will be issued for duties or unused shipping fees.
We strive to provide clear communication and ensure your shipping experience is seamless. If you have any questions or need assistance, feel free to reach out to us at: info@lestissees.com

DIGITAL PRODUCTS: NO RETURNS OR REFUNDS
All of our sewing patterns are sold as digital PDF files and are delivered instantly after purchase.

We strive for excellence in our products and customer service, but some imperfections may occur with fabric.
Please note that stains, holes, or blemishes within 3 inches (10 cm) of the edge are considered acceptable. Missing or pulled knit stitches on the wrong side of the fabric that do not distort the face are also considered acceptable. Additionally, fabric cut at 1 to 3 cm from the edge is acceptable. Stains on the inside of the fabric are also acceptable if they do not appear on the right side.
Please be aware that fabric may shrink after the first wash, so we recommend purchasing slightly more than the exact length required for your project.
We cannot cancel or refund orders once we've cut your fabric. If a refund is necessary, a 5% administration fee of your total bill will be charged.
We cannot offer refunds or compensation for items purchased a few days before they go on sale.
If a product is sold out, we'll contact you immediately to offer either a refund of the item at the price you've paid or a replacement with a product of equal value.
