Asalaam Aleikum,
The points you mentioned about men have already been addressed. Men should also dress modestly. A HUMAN with dignity and honor clothes himself/herself properly.
I think the main reason you find it "unfair" is because of the western ideas of equality. We should be able to do the same things men do right? Actually, that's not quite true. We are different creatures with different needs. If we all had the same rules and regulations, it would be very unfair.
Equality and Equity are not the same thing. Maybe if you internalize this and learn to appreciate and love the creation that you are, it won't feel so negative for you, insha'Allah.
Also, nobody said covering up meant always wearing black or dull colors. Pick your color according to your surroundings as to not be singled out. I find that in big cities or in large crowds here in north america, wearing all black makes one stick out like a sore thumb lol. My husband actually encouraged me to choose other abaya colors... it took me a while because I'm an all black type of gal, even before Islam :embarrass
