Fabric suggestions
• Drafted for medium weight knits (200gsm +) with 4-way stretch, great recovery, and a minimum 50% horizontal stretch, and 50% vertical stretch. Look for high spandex content, 5% minimum, but I prefer 12%-25%. Note- the higher spandex content and heavier weight knits (250gsm+) will feel tighter and give more compression.
• Peached performance fabric, Nylon spandex (not swim fabric, but athletic fabric and look for higher weight), athletic knits- athletic ribbed, athletic brushed poly, etc.
• I like to self line my Demi, but you could also use another similar weight athletic knit for the lining. You do not want to use a different weight or stretch fabric for the lining, it will not work well.
• For the separate sports bra- optional innerlining for added support OR removable cup option, you will need power mesh or power net.
Supplies
• All options need 1/4″ clear elastic for added support
• Sports bra option- 1″ knit elastic and optional- sewing cups for the removable cup option
• Optional- 1/2″ wonder under or knit hem tape
• Basics: thread, pins or clips, scissors, ruler, hem gauge, safety pin or bodkin, and marking tool. Ball point, stretch, or jersey needle.
