I'm 5'4", big waist, no hips, narrow shoulders, 36DD bust. Take a size 14/16 - depending on the shop, the shape, the fabric etc. Find that stretch jersey dresses with cap or 3/4 sleeves suit me best. I never go longer than knee length, (too frumpy!) & often just above. I wear with a cardi, thick black tights and black suede ankle boots with a 1&1/2" heel in winter then fake tan my legs & wear with sandals in summer. Or I might wear black leggings with knee boots & a thigh length tunic dress in winter or Capri length leggings with sandals in summer. Sometimes a,fitted skirt just above the knee with thick tights, boots, coloured vest & fitted cardi. Anything with a,bit of stretch is good in my book! Have given up on the very casual items, including jeans, those awful cropped summer trousers and tshirt combos as they just make me look scruffy now I'm older! A nice patterned pashmina or scarf is always a good accessory if worn in the young style, but no frumpy granny knots lol. And I adore a long pendant necklace ?. People scoffed & Trinny &Susannah but I found their books really helpful. Plenty on charity shop shelves now!
