So you haven't got arms of steel? Don't worry...
Do -Stick to three-quarter-length sleeves when buying blouses (elasticised ones will cut into you). Long sleeves and floaty cuffs are a winner, as are feminine bracelets like a delicate chain. You can also get away with thin knitwear and smocks.
Don't -Go for chunky jewelry, elasticised or short sleeves, and thick woollen knitwear.
