lot of 2:  1 youth & 1 adult (black) amish bonnets.   Purchased from Northern Indiana amish families.  Strings ARE  attached.  Smallest 5-1/2" front to back and 15-1/4" string to string.   The other is 5-1/2" x 16-1/2".  It would be best to measure. I am guessing the small one fits 8-12 year old, then small adult for the larger one.  Questions welcome. Thanks for looking. Bonnets are held on by straight pins, double tape or bobby pins.
