I'm 46, 5'5" and size 14 (although on a diet
) have big boobs (34F) and a short non-existent waist/body. Apple shape but not bad legs. Wedding is at 4pm but I'm guessing it'll still be baking hot, and we have to walk 20 mins to reception venue down a steep hill so in my mind I'm thinking longish floaty cool dress with nice flat sandals rather than hot sweaty mess. Bride is in white so obvs need to avoid that, although could white linen trousers with pretty top be acceptable? Suggestions please oh wise ones?
