I'm going to tell you the biggest secret about clothes and I'm going to blaspheme and tell it like it actually is. So gather 'round my gay brothers and I'll share with you the key to all gay fashion.
It's very simple, and it's true of straight fashion as well:
The person makes their clothes attractive. Their clothes do NOT make them attractive.
The same pair of jeans on two different people will look much different and wear much different. They will appear to be more or less attractive depending on who is wearing them. So look for clothing that promotes your attributes, both physical AND personality-wise.
