Make a beginner friendly, simple one-piece swimsuit with this free PDF sewing pattern.
Simple One is a comfortable swimsuit pattern from size 36 to size 52.
It is designed for 4-way stretch swimsuit fabric like Lycra, stretch polyester featuring a crosswise and lengthwise stretch of 50%.
This sewing pattern is designed to add a 4-way stretch lining at the front and back. You can leave out the back lining if you prefer, but be aware of transparency.
Choose the best size according to your measurements.
To better adapt to all different heights, this pattern has two different versions in all sizes. The difference is the length of the pieces. Before you begin printing your pattern, please consider how high you are.
For the best result, first do a fit test using an inexpensive fabric.
Make sure everything’s okay. Make modifications if necessary and cut your precious fabric when you are satisfied with the result.
Don’t worry! No one’s got the standard sizes. Look at me. I’ve got size 38 in the bust, but 40 on the waist and hips. I use size 38 because it is a stretch enough to cover these extra centimeters at the hip.
If you are between two sizes choose the smaller one, the stretch fabric will allow it to stretch a few centimeters. If the difference is larger than one size consider adding a few centimeters more where it is needed.
Note that elastics will make you feel your swimsuit more fitted. Don’t worry if it is gaping at the armholes or other parts before adding elastics.
This free pattern is available with instructions in English or Spanish. Choose what’s best for you.
