96 POUNDS AT 5 FOOT AND 3 INCHES!? GIRL YOU ARE NOT FAT!!
Seriously, that is skinny!! I'm five foot four, and I'm 120 pounds. Don't even XD
Maybe tight fitting clothes don't exactly match your figure. Ofc, it can work for every figure, you just gotta find the right pants and shirts that pair well.
Girl, you're so pretty just the way you are!! Don't let anyone tell you different!! Also, can I tell you a little secret?? Dressing room mirrors and rooms are awful- the lighting makes even the skinniest girls super self-conscious XD I also thing you might be psyching yourself out, and that you really are perfect :)
Best of luck :)
