Nightmare, isn’t it?
I tend to wear slightly looser-fitting tops and look on eBay for second-hand clothes from nicer brands than I’d normally buy because I find the quality of their lighter-weight clothes to be better than the quality of lighter-weight high street clothes, if that makes sense? Thinner material from places I’d normally buy tends to pucker, or be see through, or just look cheap, so I tend to search for The Fold, Hobbs etc.
Camisole and a lightweight cardigan makes me sound about 90, but in the right style it looks smart and doesn’t feel too heavy, plus you can take the cardigan off when the shoulder police / creeps aren’t around.
Instagram is great for workwear ideas, hats off to those who manage to make a maxi skirt look professional; it’d be great to get a bit of a breeze around the essentials, but I’d look such a tit rocking up the office in anything floaty on my bottom half.
Having said that, two fans on my desk and trying to avoid meetings too far away from my building are the best things to avoid getting too hot
