I tried on the shorts last night in a more realistic situation i.e. without jeans on underneath.

I think they'll be fine for most of us. I have pretty chunky thighs too, though not on the same scale as Lewis and they were fine around my waist and fine around my thighs, they just don't flap around like the old shorts. So I think they'll be good for most of us and I got 4 pairs of larger ones so we can try stuff on on Thursday and then I'll exchange/buy more as needed.

Getting the socks swapped too, phew!
