I would second snag tights chub rub shorts! Wearing them the past few days has been great.
I donāt wear them myself, but have friends who swear by Snag Chub Rub and Popsy Longpops. Apparently both fit over bumps if you size up one.
I have the Jojo mama baby ones you can buy online - they are comfy and do the job!
I've just got some delivered from new look they have maternity ones x
Not shorts but I swore by liquid talc when I was heavily pregnant with my first in summer 22 (it was a bloody hot one that year!) it works so well and I just used to Asda own brand. It definitely stops the chafing feeling x
Snag tights do good ones! They go plus size so would size up over bump
