If they're going out for a nice dinner or with her parents or to anywhere in public it absolutely matters if they match. There's nothing wrong with expecting your partner to look presentable. I've completely changed my fiancé's wardrobe in the 3 years we've been together. He swore I'd never get him in a polo and now he loves them and wears them all the time. Now he only wears his Metallica tshirts to work since he works in a warehouse. Obviously OP's done more to drive her man nuts than ask him to change his clothes though.

You don't have to match to look presentable.

If he was wearing a striped shirt with plaid shorts, he'd look utterly stupid. They don't have to match perfectly but if they look stupid or clash or whatever then there's nothing wrong with asking him to change. I wouldn't let my fiance embarrass me in public so it's no surprise that OP would either. However she probably has been doing other nagging and whatnot to push him over the edge.

You can totally try to change things about someone you love. It's not always for your own benefit. Getting a guy to change how he dresses so that he looks presentable and mature only helps him out in the world. Who would you hire? The guy in dirty jeans and a band tshirt or the guy in khakis and a polo? Some guys need a little help growing up. There's nothing wrong with us girls trying to help them be better people.

107 -God, stop. I already want to throw your clothes out on the sidewalk and I am not your boyfriend.

id definitely hire the guy in jeans. polo shirts just cry out I'm a pansy that's afraid to work and/or I'm pussy whipped by my girlfriend. Neither of which I'd want working for me.

I'd say it would depend on the job. If it was a warehouse $8/hr who gives a **** job, then whatever. If it's a job with an interview and any degree of professionalism then a guy that doesn't look the part would never be hired. My fiancé actually did get a job offer over his friend because he dressed nicer and his friend was in ratty clothes and covered in tattoos. If people want to dress in ratty clothes that's fine, but they can't bitch about it later when people look down on them.

and oh i see ur a grammar nazi ...woopdedoodledandy oh no i put 3wordz together that arnt rlly words THE WORLD IZ GONNA FALL APART AGHHH ;3

Once more, according to the FML his shirt and pants did not match. It could be anything trivial from color to texture, but we don't know that. That aside, it's for a dinner they were either invited to, decided to go have as a date, or that they set up to receive others, not a job interview in which your comment would be appropriate for. I never said you couldn't change anything at all in order to help your significant other overcome themselves or have better changes and exceed expectations, but changing little things for YOUR own benefit because you DISLIKE them is wrong. There are, in fact, situations in which you do need to dress up, but perhaps he has his own sense of style which isn't entirely wrong. But, once again, we can all only assume.
