If You are interested to try making this '60s inspired cross chest swimwear this is the pattern in sizes  XS, S, M, L ( EU  34, 36, 38, 40, 42). 
The Pattern is in PDF format. You will need to glue on some details together. The patterns don't include a tutorial on how to sew it, but there is a lot of tips on my blog which I linked.
This swimsuit design is inspired by the iconic actress Ann-Margaret look.
I  decided to make this swimsuit because I love its classic design. I love the accentuated waist. The waist details cut of this swimwear is really slimming. 
It requires about 35,5 inches or 90 centimeters of main fabric. The same amount for linen.
 I didn't use separate bra cups, so it makes the sewing process a bit quicker.
 I am really happy with the finished result! This one piece swimsuit came out really comfortable.

Best wishes
