PLUS SIZED ANATOMY??

HEY CAN SOMEONE GIVE ME TIPS ON HOW TO DRAW FAT WOMEN? SPECIFICALLY IF SHE'S LIKE SUPER SHORT. I'M MAKING AN OC (pikachu lady :]) BUT IM SHIT AT ANATOMY AND WANT IT TO LOOK NATURAL WITHOUT LOOKING SUPER EXAGGERATED OR LIKE. DEVIANTART PIKACHU LIBRE FANART BY RODENTTHIGHS26. JUST GENERALLY TIPS ON HOW TO DRAW FAT ROLLS AND THE SHAPE OF THINGS LIKE THE ARMS, SHOULDERS, ABDOMEN AND LEGS WOULD BE GREATLY APPRECIATED THANK YOU!!!!! ALSO UH FOR LIKE A REFERENCE ON MY ART STYLE I DREW HARLEY QUINN A WHILE BACK AND I POSTED IT SOMEWHERE ON MY BLOG. IT'S MOSTLY LINELESS ART, I DO ADD LIKE A FEW LINES IF I HAVE TO FOR SHADING AND SHTUFF. IT MAKES IT REALLY HARD TO DRAW ANATOMY AND, MAINLY, CHARACTERS WITH MORE WEIGHT TO THEM, BUT IF I EVER USE OUTLINES IT LOOKS REALLY BAD. ALSO GIVE OUTFIT SUGGESTIONS IM NOT SURE WHAT SHES GONNA WEAR!! MY MAIN IDEA FOR HER IS SHE'S EITHER A VLOGGER OR LIKE. IDK A CAGE FIGHTER? IM STILL NOT SURE WHAT SHE'S GONNA DO OTHER THAN KISSING HER GF
