Sewing your own underwear is empowering. This pattern is free for everyone!

Flo is a pattern for bikini-style period underwear, designed to help you use your knit scraps and create less waste from tampons and pads. They sit comfortably across your hips with a navel-grazing, mid-rise fit and average coverage at the back. The legs
and waist are finished with fold-over elastic.

Don’t need period underwear? No problem! Just skip the absorbent fabric, and Flo makes a comfortable pair of everyday underwear.

Jamie is wearing a size 16 Flo. Her measurements are 41 1/2”, 38”, 50 1/2” and she is 5’10 1/2”.

ALSO PICTURED: the Dana bra and the Jane t-shirt.
