AnnaSophia Rob, who plays a young version of Carrie from Sex In The City, wore this very casual outfit: neon orange pants mixed with a navy blue (almost black) sweater. If you'd like to wear something neon this Spring and you aren't sure about it, wear something neutral like her. She also added a flower pattern scarf which is perfect for this season and it also gives some color to the sweater although the pants are very bold.
Remember: wear neutral things with neon colors and you won't go wrong! :)
