If your days are spent in the sun (and even if they're not) you need the UPF 50+ Vero Tunic. It's a longer length knit tunic with side slits and stitching details at the notched neckline, and it was made with the sunshine-loving Lilly girl in mind. UPF 50+ Protection Because We Love The Sun. UPF = Ultraviolet Protection Factor (It'S Always A Good Idea To Double Dip...AKA, Please Wear Your Favorite SPF Lotion As Well!).
