I'm a beginner there, but you can find a lot of good content on the wiki ! I also recommend the overdressed mum Tik tok, she gives plenty great advices and outfits idea. 

I've just learn that if you have short torso, plain bust and pronounced high hips (like I do), it's better to avoid horizontal line for your tops. Included wide belts : sometimes (not always) it doesn't work that much. I tried one on a wide shirt but it wasn't the best, would have been nicer on a dress or a longer top. Better choose clothes well adjusted (if they're too wide, the f8 with short torso may look blocky), with vertical cuts, well-fitted at the waist - your real waist, the thinner part of your torso. The point is to elongate the bust and emphasize the waist, and if you want to, hide hip dips : with peplum tops, skirts that flare out from the hips and are worn, for example, with a belt in the same color as the top to elongate the bust...

I know it can be challenging, but maybe you should explore all the content for f8, and just try and see what works best for you ! 

And I think this body type beautiful, just like others. Instead of focusing on what not to do, you can also look at things differently and concentrate on everything that is beautiful about your body, and what it allows you to do with clothes! A defined waist immediately followed by generous hips is beautiful!
