I wore heels to my works Xmas do, at 37 weeks pregnant. I took them off when we were at the table, and couldn't get them on again!! I had a pair of little ballet pumps in my clutch, luckily. They were flat, so fitted without taking any room.
Id have a giggle if my shows wouldn't go back on my feet half way through the evening lol.
Lucky you had the flats xx
It was funny- they swelled up ridiculously! I only got right at the end luckily.
