Crochet Flip Flop details

I bought three flip flops at Michael's on Sunday. They were on sale for $1.19 each.
The purpose of my purchase was to use the eyelash type yarn and crochet it on the top area (toe section).
I made these last night at crochet group as I could not remember how to start. The set shown here I created for my daughter.

I plan on making another set for myself, black flip flop with red yarn so stay tuned for that version.

I tried them on and they are very soft and feel like "slippers" so not sure how it will look to wear them in public. What do you think? Perhaps too informal ? Maybe for the beach ? or pool?
