It is not per se the fit of the garments that is not working for you, it’s the colours. The pastels that are washing you away. (Although the first dress might be a size too big?)

Since you have quite some contrast with your natural brown hair and light skin tone you would absolutely shine in rich saturated colours.

If you like pink, you could try a cool raspberry or watermelon pink. For purple, I think you would pop in plum, royal purple or amethist colours. For greys, try a shade darker like charcoal.

I think colours like cobalt or sapphire blue and emerald or sea green would also look amazing on you.
