Pippa Middleton stepped out in a summery green dress flashing her engagement ring in London Tuesday. Kate Middleton’s sister got engaged to hedge fund manager James Matthews over the weekend.

The 32-year-old wore the chic dress flaunting her slim figure and her $262,000 engagement ring, according to pictures posted by Express. Pippa styled her look with navy open-toe heeled sandals and matching bag. She kept her hair loose and completed the look with black shades.

After Pippa and James confirmed they were engaged, speculations began when the wedding will be and whether it will match Kate’s wedding to Prince William. Debate about Pippa’s wedding dress is also ongoing.

“My instinct is that she will chose British,” style expert Hilary Alexander told People magazine. Alexander added that Pippa would be mindful of any comparisons with the Duchess of Cambridge’s ivory lace dress designed by Sarah Burton at Alexander McQueen.

“She won’t want her bridal gown to compete with Kate’s – the wedding dress of the century!,” Alexander told the magazine. “She could go for something lavish and romantic by Marchesa or upmarket luxe by Ralph & Russo,” Alexander noted, adding, “Other possibilities include Temperley, which both she and Kate wear regularly or Jenny Packham.”
