Um... well... I dunno about y'all... but I've found that wearing things over my diapers actually makes me sweat more. My typical workday atire is diaper, baggy shorts, & a long t-shirt. The fewer the layers and the looser fitting the clothing... the better off you are. I realise that this is not always practical for everyone b/c of work dress codes and the like... but I'm out in an open warehouse all day with no AC... so it gets plenty hot.
