The best fitting swimsuit I’ve ever owned!

I had a completely open mind when starting this make. Mostly because Cashmerette fitting guides are so good. so I just followed exactly the measuring guidelines and the fit was perfect first time!
I’ve not sewn with bra foam before, or successfully made a swimsuit. I’d made the Marblehead tankinis before, and sewn a Willowdale bra. This was so much easier.
I used a toile swimsuit fabric and lined it with powermesh from Pound Fabrics UK. Bothe were good quality but inexpensive.
The bra foam was obtained from Etsy and was a little more pricey, but as very little is used it will last me ages.
Even carefully following each step of the instructions and measuring twice, it was a relatively quick make.
I couldn’t quite believe it when I tried it on. I’m not sure I’ve ever felt so good in a swimsuit!
I could move easily and jump up and down. Everything held in place beautifully.
I was particularly intrigued by the torso measurement technique. I had to add a little length following the guidelines. It was perfect.
I can’t wait to make more…
I recorded a vlog about the make with photos of the results, which can be found on my channel @clarobobbins.
Happy sewing💕

Great versatile swimsuit with excellent support.

This was a great make, the instructions were easy to follow, despite being my first time using lingerie foam. It was also very good in terms of length - I have found some swimsuits graded up from a smaller block lack this.
I like that the design has a good amount of coverage, both from the perspective of sun protection and to keep everything inside my swimmers for when I do laps at the pool.
The only thing I'd change next time - and this was my fault not that of the pattern - was that the foam I used lacked stretch, so it made the neckline difficult to get in and out of. For my second make of this I've purchased scuba fabric.
