Rules for working with patterns
Biflex and 4-way stretchable velvet - sew according to ready-made patterns, where the stretch coefficient has already been calculated
In thick biflex and velvet, we sew panties in 1 layer and sew on a gusset, in thin biflex and lycra it is recommended to sew a double front (or double panties entirely)


Regular velvet - take the back pattern separately and the front pattern separately, put the actual value along the arc, because the fabric does not stretch in this direction. For psh-2 - focus on the values on the biflex pattern

I would also like to add that there is a request "I want narrower straps". We are trying to dissuade from this option because narrow straps will slip off the waist, despite the silicone (narrow - these are straps narrower than 1.8 cm)

    Work process
1)   1) We calculate the measurements (hip circumference and psh2) based on the planned kilograms to be lost (interpretation of measurements)

2) Select the required patterns according to the table

It is also recommended to use this table when you sew swimsuits for sale for availability (normal hip circumference 89-94 and medium fit)

Comments
If the arc is large (48 or more, and you don't need to subtract anything from the tables, you can manually gather
 3-5 cm along the central elastic band and thus you will subtract another 3 cm, and if it turns out to be too little, 
you can always cut it off and return it to the original value) 
When determining how much to subtract from psh-2 on drying, note that I divided the fit of the panties into medium 
and high and formatted them into different tables
