Office friendly polish

When it come to picking nail polish I usually go for the brightest or most glittery polish as working for the Boys and Girls club my nail polish colors aren't going to offend anyone if anything it keep my kids attention as I point to their homework lol.. But I sometimes have important meetings that I need to have office friendly polish and I struggle to pick them because I don't have many. I had an important meeting a couple of days ago and I chose Sinful colors Social Ladder. Its a shimmery light kinda nude pink. I liked the color a lot but Its not me so after the meeting I took it right off.
