I cut off the collar so I can wear it later with some cute collar chains <3

lay shirt flat & cut across straight under the armpits

Turn it inside out & pin for the hem :)
Leave space for the garter to fit through

Sew Sew Sew <3

After you sew the hem - this part should still be open.
Push the garter through
I use a safety pin and try my best to push it through

Sew the garter together when the two ends meet.
Sew the opening shut :)

Put it on <3
