Dorothea Hutchinson
High-waisted bikini option

Instructions were clear and easy to follow, especially when combined with the Sewalong information on the Megan Nielsen website.

It has a slightly vintage vibe but is the design of my dreams, combining high waisted pants with a sporty bikini top.

I made a 12 top and had to grade between 12 hip and 10 waist for the bottoms, then cut down the back slightly to make it level around my waist (and account for my slightly rounded abdomen aka pot belly). I also had to reduce the waistbands and underbust bands by 0.5cm (and extend the top and bottom by 0.5cm) because I could only find 2cm swimming elastic (instead of 2.5cm).

I used fashion fabric from Newcrafthouse, who also has amazing swimming elastic. The lining is from funkifabrics. I had to hand baste it together ahead of using the sewing machine (because the seam allowances are so small and the fabrics so slippery).

I’m very happy with my first swimming costume attempt!

Megan Nielsen Cottesloe Swimsuit

A great pattern with lots of options. I've made the higher back one piece but will try some others too. This was a toile made with fabrics left from the two swimsuits I sewed last summer.

Adapted to include a pocket for a breast form in the shelf bra for a mastectomy friendly option.

I made some small changes so that the shoulder seams were enclosed. Next time I'll line the entire front of the suit with power mesh for a smoother finish when wearing it.
