Awww That's adorable. Have def seen some male friends who're fathers have their hair up in pigtails and their nails done in pink because their daughter wanted to play beauty spa with them. Anyone asks they just laugh and mention their kid.

Like all anyone is going to think is that you're a good parent, that's if they even notice or care that your nails are done. I genuinely don't know anyone who would make such a hullabaloo out of something so minor.
