The common masses like myself have a hard time telling what is just nice cloths you got at Target and a suit you paid a few grand for. I think you’d be fine.
I felt this way until I actually saw it in person. Most guys will notice this as friends/colleagues start making money while we're still in school/residency (can't speak to women's fashion, personally). It took me a few weddings in my late-20s to realize that small upgrades can go a long way and that bottom-barrel fashion looks bad in more formal settings.
It's hard to tell the difference between designer pants that cost $200 and some Banana Republic slacks you got on clearance for $35, but at some point you'll have to upgrade from the ill-fitting Target/Old Navy styles your Mom bought you growing up, especially for things like shoes, jackets, button downs, etc...
Obviously fit > style >>> brand, so get a good tailor for your more formal stuff and learn which styles fit you. However, you'll definitely notice the difference between the look of some Allen Edmonds with full grain leather and actual stitches vs. a $60 pair of Clark's with plastic-y leather held together by glue. Same for belts, jackets, and button downs.
The docs I know who wear high end clothes and drive high end cars are almost invariably dumpy, balding, middle aged guys (or older). I don't judge them for their choices, people are into different things, and on some level it must be nice to enjoy the fruits of their labor in such a way. That said, some of them would be better served by investing in a gym membership.
Maybe my above reply should have said fitness = fit > style >>> brand. A lot of people debate over which scrubs brand looks best, but the reality is that really fit people make a potato sack look good. A good body is easily the best accessory if you want to look sharp in scrubs.
I'll be honest outside of cosmetic fields where your appearance does matter, I kinda judge doctors who really dress up for work. This is doubly so if its a hospital based job.
Not necessarily rational, but every time I've met a doctor who goes to work in a suit they have ended up being somewhere in the jerk/narcissist/<insert other negative trait here> spectrum.
These guys are dressing too formal for the occasion and mistaking that for style, and it's not surprising that missing that detail goes right along with social incompetence/behavior issues. I don't think there's any problem with wanting to dress up (it's fun to look nice!), but it has to be appropriate for the occasion.
If you want to up your style, you don't "dress up" by upgrading to some Brunello Cucinelli suit with Italian shoes. That's tone deaf. Keep the same formality but add accessories and improve the fit and quality of the clothing. Get pants that fit. Replace a plain white button down with something with just a bit of flourish. Upgrade from plain oxfords to wingtips or cap toes with high quality leather and Goodyear welted soles, and take care of them. Get socks that bring out accents elsewhere in the outfit. Add a watch (not a Rolex). Iron or at the very least steam your clothes after washing.
All this can be done for extremely cheap too if you're willing to look at the used market and you know what to look for (especially in shoes, there's
a lot of bad stuff out there). It's a skill worth learning if you want to look nice without worrying so much about ruining your clothes.
