My colleague completely avoids weighing herself but has TheTrousers of Truth, a brutally simple concept: you choose a flattering but slightly uncompromising pair of trousers and either wear them or try them on regularly - if they fit, no action needed, if they don’t - have a word with yourself.
So Every Single Day of lockdown, I have worn leggings. Nice ones - thick ones, high waisted ones, some Lululemon ones, the sort that are called “compression” or “close hold” etc. When feeling giddy and in need of variety I have cracked out the Uniqlo joggers. So obvs my “sense of waistband” is entirely skewed. In practice for some imminent light socialising I have put on a pair of trousers (ie ones with no stretch) for the first time literally in a year (Mint Velvet Biker skinnies, I think). Oooof.
Result/observations: Well, I can get them on. Let’s just say that they won’t need a belt as I seem to have my own internal pressure system holding them up. I suspect I will be pretty pleased to take them off at the end of the day. I’m calling it a score draw, which actually isn’t that bad a result.
(I haven’t tried a underwired bra yet - too much at the same time!)
