I was looking for a simple bun net with elastic at the base that I could stretch over hair buns for work and play (not a dancer) and that would be quite inconspicuous. These are exactly what I was chasing. I found that I can create a bun with just a hair band, then stretch the KySienn Bun Net over the top - no pins required.
Thanks for the bonus bobby pins by the way - I'll use them on occasions I plan to play a bit harder :)
