I love a guy in a white shirt. God knows why but if he's at least a tiny bit tanned, and at least a little toned toned too, stick him in a white v-neck or a crisp white button down with rolled up sleevesand yeah... Sexy as owt.
Fit to your body. Thats the main thing. look up some celebs or models who look simular to you, look up hair styles that suit some clothing scenes and you're set. But always fit to your body. on a guy, not too tight, but not overly loose, meaning, no two sizes bigger jeans where your ass looks non-existant. And please wear a belt so we dont have to see your underwear haha
Fitting suits, fitting jeans and a black dress shirt combo, fitting jeans and a white tee not very tight are my fav things to see on guys ah and I also love worn out t shirts of earth tones with spiders and sculls on my bf:-)
