How To Style And Wear Your Jeans Pattern

This denim jeans sewing pattern will be a worthy fashion ally to all your future warm and cold-weather dressing decisions. It's evident that flare pants add a graceful, curved silhouette to your already gorgeous, feminine figure. Plus, they also add length to your legs at the same time.

You can keep it simple with a graphic t-shirt or try a smart casual style with an oversized blazer or shacket. Turtlenecks are also a fantastic addition to any flare jeans ensemble - just make sure to tuck them in. Layer it with a leather jacket or opt for a cardigan - the sartorial options are endless. For afternoon dressing, opt for a see-through top, layered on top of a bodysuit or a skin-tight strappy top. You can always add a classic shoulder bag or a tote to the mix.

How To Make Flare Jeans

Alesia is a high-waisted stretch denim pants pattern with pockets. To help you on your way, we've put together this simple guide with instructions and tips to make sure your pants turn out exactly the way you want them.

jeans sewing pattern

Supplies needed:

  • Your Alesia Denim Pants Pattern
  • Preffered fabric
  • Color matching thread
  • Sewing machine
  • 1 zipper for pants 15-18 cm long
  • 1 button
  • Interlining
  • 4 eyelets for the front pockets

Seam Allowance:

  • 2.5 cm hem
  • 3 cm on the upper part of the pockets
  • 1.5 cm rest of the reserves of the pockets
  • 1 cm rest of the seam

Suggested fabrics:

To start, you have to make sure the fabric you use has a little more stretch to it. That's what will keep your item fitting comfortably and looking good! Consider a medium weight woven fabric with 3-6% elasticity, suitable for trousers (stretch denim). Selvedge denim is also a great option if you can find it in your area

How much fabric do you need for your diy flare jeans? 

You know how sometimes you buy some fabric and you're like, "Ah, yeah, I'm definitely *sure* this is enough!" And then once you start cutting it out and you're like, "This is definitely *not* going to be enough"?

Check out the chart below to make sure you get the right amount of fabric for your size! The amount of fabric you'll need is based on the standard useful width of fabric, between 140 and 150 centimeters. So if you're using a different width or pattern like stripes or prints - adjust the placement of pieces so that the finished garment will fit correctly to the available width.


You know that annoying feeling when you spend all this time and energy on making a garment, sewing every seam perfectly only to have it shrink after its first wash? Not cool.

To accurately cut your fabric, make sure that you test your fabric's contraction before cutting it. To do this, iron steam the material following the heat recommendations printed on the fabric.
