Everyone is beautiful in their own skin tone WTF do U make yourself fair on social media (girls mainly)

This isn't fair when sending pics to groom's family they edit it completely and send, then when they go to see her they apply hell lot of makeup and make her look completely different. But after marriage he's gonna see the her won't that be considered cheating?

Until marriage girls have diet, control their weight but after marrying BOOM they get fat (it's comman to put on weight) but why can't they workout and stay in a good shape. I'm not saying she should be like a model, but give the same effort you made earlier even after marriage
