Jennifer Lopez can wear anything and look good, but when she leans towards a look that is pastel and feminine, it wins our hearts every time. Case in point: Wednesday night’s episode of American Idol, where the judge wooed us with her sherbet dress ($87; asos.com) and sexy neon Sophia Webster shoes.

She completed the look with a dewy glow and a wispy updo. “To create tonight’s look, we blow dried her hair straight with a Mason Pearson brush,” hairstylist Lorenzo Martin said. “Then we flat-ironed it and sprayed in Oribe beach spray. After that we put her hair in a ponytail and wrapped it around as a bun and pinned in.  Then we pulled out a few front pieces and used hairspray to finish off the look.  The updo worked perfectly to accentuate the details of the back of her dress.”
