Right, I look dreadful in photos based on wearing the wrong clothes. Help me!

Just had a family gathering at which I wore my nice new casual outfit and looked nice...or so I thought. There are videos of me looking perfectly normal and reasonable, and photos where I look like a sack of spuds.

I'm a lot fatter than I think I am (5'5", 12 stone, size 14, big boobs) - in mirrors, I look fine. However, in photos today I was much wider than I realised. I was mistakenly wearing a pale top with horizontal stripes (I know; I should have known better).

I'm obviously not going to lose 3 stone before Christmas when more photos will be taken, so I need to choose better outfits. What can I wear that will make me look less wide and lumpy?

Black always black! Although i am
sure you don’t look as bad as you think a size 14 isn’t large.

Thank you! I honestly don't look awful in real life - the videos from the same event are fine. But I need tricks to make sure that photos come out nicer. I do like black! Not so festive, though. Maybe I also need to learn how to pose.
