I think men typically wear 1 outfit per day if they are not working. Whatever they start out with is it barring some formal event. Women will often change if they leave the house.
So then, you are recommending that he just not put the sweats on in the first place? 
What kind of freak doesn’t own any jeans?
Me. Not a single pair.
And I totally agree with the OP: my husband stays home and takes care of his mom, and he would never wear sweats while out.
I’ll tell you what bothers me as much as the sweats - it’s the baseball cap. Baseball cap to me means “I couldn’t even be arsed to wash/comb my hair.”
But I hate baseball caps with a passion and am so so SO glad my SO doesn’t ever wear them.
ETA: For years I never owned any jeans. I still think they are a bit on the casual side, though I will actually wear them now - but I would never wear jeans and a t-shirt to work, for example. If I am wearing jeans on a Friday it’s with a pretty blouse.
It can also mean “balding and in denial”.
Re: zoris (‘flip-flops’, ‘shower shoes’). Around the yard only. I’ll wear sandals in the Summer, like Tevas or a ‘nicer’ zori-style, but only for casual activities and never with sweats.
Bald, confident men are sexy. MEN, DO YOU HEAR ME???
Post of the day. 
People with skanky toes should not be allowed to wear flip-flops. Squicks me out. I don’t want to see your nasty toe nails and cracked heels. If you can’t do it yourself - go get a pedicure. Even if you are a guy - they will buff off the dead skin and trim your toe nails. But I really, really don’t like to see men’s feet in public. Just weird.
Fortunately, my bf wears the one kind of mandals I can stand - where his entire foot is practically covered, just enough space for ventilation.
I should only have to put up with seeing your nasty feet in aquatic settings after Memorial Day and before Labor Day. Ewww!
I wore baseball caps a lot right after I started shaving my head. It prevented sunburn. Gradually, I reduced their frequency in my wardrobe.
Now I wear my Tilley hat when I need a hat.
Well, the flip-flops are nothing I’m ever going to convince him to not wear. He’s Pacific Islander, and all his relatives wear them pretty much any time they’re not at work and it’s not raining. (We’re in L.A., so it’s rarely too cold for them.) I don’t mind them, though I don’t like to wear them myself unless it’s very hot, due to blister-between-the-toes.
I think some of the reason this bothers me so much is the fact that one of the things that attracted me to him many years ago (when we were both skinnier) was the fact that he was a bit of a peacock. Always took care in how he dressed, always in black dockers and button-up shirts (Hawaiian shirts for casual, dress shirts for anything, well, dressy). So there’s a sense of loss there, mixed in with it - which I thought might be influencing my reaction and making me harsher on the sweatpants than was called for.
Okay, I am revising my answer as follows: I reserve the right to be a total slob, and no one should think any different of me because I exercise this right freely. I wear what I feel comfortable in, and if the rest of society doesn’t want to join me on Planet Crazy, they are the ones with the problem, not me. Conformists!
That’s why I said “can” rather than “always does”.
Sweatpants should only be worn preparing/during a workout. I’m not sure I get loungewear either. Sweats/loungewear should not be seen by others.
Thank god he wasn’t wearing these. These types of pants are a travesty. I can’t believe my eyes when I see people wearing these…in public! Oddly, I see them (too) frequently worn by the scalpers working the corners around downtown.
Mind you, I’m not one who should be judging. I can’t distinguish between the HOT/NOT outfits in my wifes ragmags (US, Hello,People,etc.)
This attitude is not far from what the kids these days actually think. Replace “slob” with “skank” at will.
It is also one of the reasons I was attracted to my SO. He dresses so nicely, all the time - button down shirts all the time. Sometime this can be over done, like last night our landlord’s maintenance guy knocked on the door at 7 PM, and I came to the door in a t-shirt and my PJ’s - but he changed to jeans and a t-shirt before he came to the door. But I still find the habit cute and endearing and not annoying.
I would be harsh, too, if he suddenly started going to public places in his sweats.
Unless the Dope is willing to add “while out for a late walk around the subdivision” to Appropriate Times to Wear Sweatpants, I am in trouble.
But I am hard pressed to come up with an occasion where jeans would be appropriate and sweats would not. I am talking about slop jeans, not the dress kind. And I tend in the direction of over-dressed rather than under.
Regards,
Shodan
These are actually “chef’s pants”, which I think (hope) is the only reason they are still around. They do have a purpose, but aren’t really meant to be seen by the public.
At least get him a pair of these.
I still wouldn’t wear them off-property.
A baseball cap can also mean “I shave my head and don’t want skin cancer.”
