He (or she) could actually be attractive with some simple changes.

• Ditch the nerdy glasses, not working for their face. Contacts are cheap enough and switching back and forth with glasses changes your look, very cute.
• Get a decent hair cut that suits them. Find a stylish people like and go there. Gay dude at Walmart used to cut me, damn I looked good. If you’re a man, find a gay stylist, best ever. (He moved. Stylists are like gypsies, gotta get their personal card and follow 'em around.)
• Dress nicely. And dressing nice costs almost zero money. Stunning what you can find at the thrift once you land on a style that’s attractive on you. I make plenty, but I still mostly dress out of thrift stores. Got a nice collection of watches for example. Got a sack of cool ones for $1 at a roadside thrift. A couple of $.75 batteries and some polish, nice.

Probably lots of others easy/cheap things. My dentist made mouth molds for tooth whitener. $80 for molds that last forever, buy the cheap refills on Amazon. Done. And what a dramatic difference two treatments makes.

The nose is a little much, but work with it. I started parting my bowl-cut hair in 8th grade. Read that dudes with a big snoz shouldn’t do that, part on the side. Stuff like that.

They’re not fat, so there’s not that to overcome. Nice chin and hands, smile and mouth. Take his/her ass outside and move around. A little color and muscle tone is easy with quick results.

tl;dr: I’ve rarely seen a truly ugly person. Almost everyone can be at least modestly attractive, easily and cheaply.
