I find it really hard to look smart in hot weather and have no idea jow to dress for the heatwave this week at work! Secondary teacher so I have to be covered - knee length skirts, nothing low cut, prefer to cover upper arms. I'm a size sixteen hourglass and found it much easier to dress well in the summer at my pre-baby 12 but haven't lost the weight I gained in pregnancy (over a year later...oops!) Am a 36HH so usually have to wear camisoles under dresses to make them decent but layering is torture in a hot classroom full of sweaty teenagers! Suggestions gratefully received!
