I made this apron several years ago for myself. It is made with cotton broadcloth, cotton torchon lace, and cotton sateen ribbon.
The heart is detachable with buttons.
There are some small holes on the front waistband where I initially sewed the buttonhole in the wrong place. This is covered by the heart.
All seams are enclosed or serged.
The fabric has some worn feeling due to age.

Apron skirt length 42 cm + 4 cm waistband
Strap length from waistband to button 78 cm (the straps are designed to be worn crossed over in the back)
Heart is about 30 cm tall x 31 cm wide (including lace)
Waistband length 53 cm
