Okay, this is the most important thing about trying feminine things and failing:
Don't take it personally.
Basically, not everything feminine works on everyone. You have to find your own style, and you have to find what works for you. When I first started transition, I really wanted to wear cute things. Pastel colors, tank tops, cute accessories, nerdy t-shirts, etc. But my bone structure, hair color, build, and skin texture wouldn't allow it. So I kept experimenting and experimenting and slowly discovered that a more elegant style, with deeper reds and purples and royal blues and basic business-like black and white, looked much better on me.
So yeah... don't go into that destructive mindset of "NOTHING works on me!" No. When something doesn't work, it just means that you need to try something else until it does work. And it takes time, and it takes a LOT of trial and error.
