How do I download my PDF Pattern?
First, we suggest creating an account in our shop so you can access all your files in one place at any time!
After you place an order, you will land on a page with a custom download link. You can download your pattern then, or use the link included in the order confirmation sent via email. If you don’t receive a download link via email, please check your junk mail as it may have been rerouted (and add us to your safe senders list so it doesn't happen again!)
Am I charged for taxes?
All Canadians are charged GST and possibly PST depending on where they live in Canada. We do not charge taxes in the US.
Customers based in the EU and UK will also be charged VAT on all goods. Regulations have changed in recent years requiring VAT to be collected based on where the customer resides (and not where the company is located) so we are legally required to collect and remit VAT even though our company is based in Canada. You can read more about the VAT regulations here.
What currency will I be charged in?
Use the dropdown at the top of our menu to choose USD, CAD, AUD, GBP, or EUR dollars to view prices and checkout in the currency of your choice.
For AUD, GBP, and EUR currencies, the price you'll see is linked to the daily exchange rate between USD and your currency, which means prices may fluctuate. For our Canadian customers, we have established set prices that will not vary with exchange rates.

Most shipping services we offer come with a tracking number. This will be sent to you via email you once the order has been processed in our warehouse.

My jacket worked up beautifully! I’m going to sew another one. Thanks!
I’ve always wanted to learn how to sew a tailored jacket. This pattern was so easy to follow and I specifically chose closet core because I love how easy their instructions are to follow. I’d highly recommend using this pattern if you want to make your first tailored jacket! It’s a well designed jacket and I love how mine turned out!
Clear, detailed instructions. Picked up some useful techniques. I did have to adjust the body and sleeve length quite a bit as I am only 5’2”. ( there are no adjustment lines on the pattern - these would be helpful). The fabric I chose was a washed linen with a liberty tana lawn lining. I omitted the pockets because I didn’t want them to distort the blazer front however I did make the welts so it looks like there are pockets.
I also ran a satin binding between the lining and facing. I will definitely make this pattern again.
I’ve made a number of blazers and jackets for work, and this pattern is very well designed and professional, with very detailed instructions. I highly recommend getting the associated notions kit.
This is my 2nd jacket. The first one had some sizing and user errors. (orange fine wale cord, was epic fabric!) I used a too-stiff interfacing on the first one, so this one i softened it up. The orange one i made the C cup and it was too big, even though i did create a muslin for sizing. I did find the C-cup dart too sharp, it needed some modification to not be so 'pointy'; the teal one i used the standard front and not the C cup. The pattern was well designed and well instructed. I wore this to a Chamber of Commerce event last night and received many compliments!
finally I left away jasika pattern for myself :too much modifications on front pattern
