If your summer plans include traveling to a beach destination, you’ll want to add this sewing project to your list. In this post, I’m going to be reviewing the Bernice reversible one-piece swimsuit by Sirena Patterns. This pattern is available for purchase on MoodFabrics.com. This classic one-piece is so much more than it’s simple silhouette! Besides the amazing fact you can totally make it reversible, the criss cross straps add just the right amount of interest to the back. It’s like having two swimsuits in one! Be sure to check out the quick video of me sewing this beauty together!

• 1.5 yards of Lilac Matte Tricot w/High Compression

PLEASE NOTE THE SIZING CHART BELOW IS FOR SIRENA PATTERNS ONLY!!

All seam allowances for the Bernice Swimsuit are 1/4 unless otherwise stated. See the chart below for sizing specifications.

I really like that Sirena Patterns come with a detailed booklet complete with step-by-step sewing instructions. The booklet also has helpful information regarding the supplies and tools needed for your project!

One tool that wasn’t listed that I feel is an absolute must-have, is a loop turner. I find it helpful for turning those tricky straps. You can purchase your loop turner from Moodfabrics.com.

Helpful Tips: 

• It’s always a good idea to record your measurements before cutting out your pattern. The important measurements for swimwear are your bust, waist, and hip measurement. Then choose your correct size accordingly.
• Using a serger is helpful but not necessary. You can achieve great results by using a zig-zag stitch or a straight stretch. The swimsuit is reversible so no seams are exposed.
• Be sure to reference the instruction booklet for how to cut out your fabric. They provide a detailed cutting layout.

I found that the sewing instructions were helpful and concise. The only part you may find a little tricky is pulling the swimsuit through the small opening. You’ll need to do this in order to sew with a clean finish. This little trick is what makes the swimsuit reversible. Don’t worry, if you take it slow and follow the directions you should be good to go!
