Fitting Coralie

Tilly and the Buttons - fitting Coralie swimwear

Making the Coralie swimwear and need a little extra help getting the fit just right? Well, you've come to the right place! This post will cover the most common fitting adjustments you might want to consider for your Coralie. 

The Coralie swimwear, designed in collaboration with Hannah from Evie la Lùve, is a simple-to-sew, versatile swimwear pattern with multiple versions to choose from. Oh and did we mention it’s got ruffles too?! With so many gorgeous variations to sew we best get cracking!

Our bodies are all wonderfully different and part of the joy of making our own clothes, lingerie and swimwear is that we can customise them completely to our shape and not have to settle with something that "kinda fits" bought from a shop. As with all sewing patterns, to get a perfect fit on the Coralie pattern, you may find you need to tweak the pattern a little bit before cutting out your fabric.

For best results, we recommend making a test swimsuit or bikini – AKA a “toile” – first before sewing in any special or expensive fabrics to check size and fit. It’s super important when making your toile that you use a fabric that has the same amount of stretch and recovery in both directions as the fabric you plan to make your final swimwear from. If it has a different stretch percentage, unfortunately it’s almost pointless making a test garment as it will fit differently. So make sure the stretch percentage is the same before you start, to save wasting your time and fabric! The fabric you use needs to have at least 50% stretch both widthways and lengthways. (Check out the supplies section in the online workshop for how to measure stretch percentage.)

In this post we’re going to cover:

Choosing your size
Lengthening or shortening pattern pieces
How to combine pattern sizes for different bust, waist and hip measurements
Full bust adjustment
Fixing a gaping seam
Adjusting the leg height
A quick fix for straps that are too long

How do I choose my sewing pattern size?

Taking accurate measurements is the first step in making sure that your swimwear will fit. The three measurements you will need to determine your size are your bust, waist and hip measurements.

Using a flexible tape measure, find the circumference of your:

Bust – the fullest part of your bust, ie. around your nipples
Waist – the narrowest point around your middle, where you bend at the side
Hips – the fullest part of your bum (not around your hip bones, as the name suggests, which is higher up)

Check the tape measure is sitting level with the floor all the way around. It can help to turn to the side and look in a mirror to check.

Inspiration and Fabric Shopping for Coralie Swimwear

Inspiration and Fabric Shopping for Coralie Swimwear

Ready for some mouthwatering ideas for sewing your Coralie swimsuits and bikinis

Sewing swimwear can feel daunting and we know for lots of sewists this may be your first toe-dip into the pool of supply shopping for this type of project. 

This is why we aren't only launching a gorgeous swimwear sewing pattern and an online workshop, we've also got a fully stocked supply shop with everything you need to sew Coralie - including all the fabrics we used for our stunning photoshoot samples!


We are stocking swimwear fabric for a limited period this summer, so be quick! If the fabric you have your heart set says 'OUT OF STOCK', click the 'TELL ME WHEN IT'S BACK' button underneath to get a notification if we restock it. At the time of writing, we have solid colours, lining and 6mm elastic back in stock verrrry soon and ginghams due back in early July.


Your main fabric needs to be a four-way stretch knit swimwear fabric with at least 50% stretch in both directions - crosswise and lengthwise. Look for a mix of nylon or polyester with elastane (AKA Lycra/Spandex). 

For your lining you can use a swimwear lining, stretch mesh or more of your main fabric, with at least 50% stretch in both directions. (If you're using main fabric for the lining though, we'd recommend more like 60/70% stretch as two layers of outer fabric will reduce how much the finished garment can stretch.) 

See above for the full breakdown of the Coralie sewing supplies!

Marcela's Lyra Shirt Dress Hack ft. Full-Length, Faux Button Placket!

Marcela's Lyra Shirt Dress Hack ft. Full-Length, Faux Button Placket!

Ready for some serious sewing inspo? We're handing the blog reins over to our newest Button recruit, our Office Assistant (and previous sewing pattern cover gal) Marcela! Marcela is known for her dreamy and adventurous sewing pattern hacks, and when we caught sight of her latest Lyra shirt dress featuring a full-length, faux button placket, we just HAD to know how she did it, and we bet you wanna know too...

Take it away, Marcela!

Marcela's Lyra shirt dress

Hi all! I want to share one of my favourite Tilly and the Buttons patterns with you, not because my face is on the cover, but more so for the fit of this pattern and because of my love for shirts. It’s the Lyra Shirt Dress sewing pattern, of course! 

When the pattern was released, I made my first version using a gorgeous viscose fabric from Fabrics Galore London, and confession time ... this was the first time I'd sewed with a "slippery fabric". Why I waited so long I will never know because it was super easy to sew with (check out our cutting & sewing tips here!). The drape in the fabric suits the Lyra pattern perfectly and I love how the final dress looks.
