The Marblehead native’s Sept. 7 show was her most mature to date, and some pieces that she showed – a beautifully intricate moss green lace dress and a deceptively simple pale rust Georgette dress – will appeal to a wide range of women. Calling it mainstream would be too crass. LaPointe has maintained her creativity but softened her edge over the past four seasons. The designer, who made a name for herself thanks in part to Lady Gaga’s support, stayed with some of her trademarks, such as black, form-fitting, full length tight skirts. Yes, Gaga will still want these clothes, but LaPointe’s spring 2013 collection, which was inspired by “a secret submarine base in Russia,” allowed the designer to play with materials such as lambskin and sueded charmeuse in luxuriously feminine new ways. Linda Fargo, senior vice president at Bergdorf Goodman, was headed backstage immediately after the show. It looks like Gaga isn’t the only one buying these clothes anymore.
