I know there are lots of people who are like "Outside doesn't matter, only the inside does!" but I find most fat people really unattractive. There are beautiful men/women out there who are overweight, but that's because their other features make them seem like they do actually take care of themselves.
In females, I find a lot of make-up, fake tan and just fakeness in general unattractive.
In men, I find having abs really unattractive. I like skinny men (& women).
As for personality, I cannot stand it when they start dramas out of small things I do, especially when they hide what they do wrong after. And when I do find out I should just be okay with it.
