When chatting with nail lacquer queen Deborah Lippmann backstage at the Kate Spade presentation during New York Fashion Week, she mentioned a quick tip I couldn’t believe I hadn’t heard before. The look she designed for the show was a white nail (she used Deborah Lippmann Silk Collection in Pseudo Silk Kimono, $19 — it’s not on shelves yet) with a silver “cap” tip (Deborah Lippmann Bad Moon Rising, $17 — available soon for holiday 2013) accented with a bright stripe in either red (Deborah Lippmann It’s Raining Men, $17), yellow (Deborah Lippmann Walking on Sunshine, $17, coming summer 2014) or pink (Deborah Lippmann Groove Is In The Heart, $17). Check out the finished look in the first photo above. It was inspired by Spade’s cap toe shoes, of course. A totally doable nail art look. Especially if you employ the trick that Lippmann demoed for me backstage on her own hand. When you want to paint perfectly straight lines on your nails, she says it’s best to set the finger you are painting flat on a table. Then, hold the brush in one spot (don’t move it at all) and simply roll your finger across the table, so the brush just glides along the top of your nail creating a totally flawless line. That’s it!
