“Sun Protective Clothing” tends to conjure images of big, beige button downs so I was delighted to find Mott 50, a new Palm Beach-worthy fashion line with UPF 50 protection (that stands for Ultraviolet Protection Factor, the clothing equivalent of SPF in sunscreen). The modern, preppy clothes are designed for poolside and beyond: Wrap dresses, shirt dresses, Kate Spade-esque bright print tunics, maxis and more, all priced between $95 and $145. There are also basic t-shirts and polos for women and men. See for yourself: Melly at the Galleria in Edina is hosting a Mott 50 trunk show now through Friday. Designer Monique Moore, a Breck School grad, will be at Melly on Friday, 11 a.m. to 2 p.m.
