Choosing the right clothes to build a masc wardrobe for starters?

So basically, i'm trying to build a wardrobe for myself with different combinations of versatile clothes. But I've been really struggling with it. I have a "hourglass" body shape. Combine that with the fact my thighs are thicker than average and that's a nightmare for me to find pants that doesn't end up making me look feminine

I'm also not very good with fashion, I'll admit. I have only recently had the courage to start dressing masc. So Ive got no idea what to look for and where to look for it. I was hoping some of you can help me out with some advice for starters
