Many times, the most effortless look is the most original. Color is huge this spring, but perhaps you aren't up for lots of color or you have a more professional appointment to make. First Lady Michelle Obama can be seen here wearing a littble black dress with a brilliant blue clutch. Also check out this Fashionsta from the Fashion Institute of Technology trying the same trend.
I spotted this Fashionista's bright neon top first. I loved the way she wore an all black pants and cardigan, making it perfect for those summer internship interviews or, if you've got that landed, for the office. She paired it with some fun strappy sandals similar to these by Dolce Vita. She also wore a small basic pendant that color-blocked with her neon top. Always try opposite colors when doing a color block; check out this necklace from Shopbop.
To get this look, try these amazing skinnies from Zara, complete with a zipper on the hem. For the pop of color try this bright yellow top from J. Crew or this one from H&M. Remember, pops of color can be done with any neutral so if black on black isn't your thing try gray or nude!
