Some fit/athletic men may need to choose from suit separates, or order a made-to-measure suit, in order to get a reasonable fit. There may be similar issues with dress shirts.
Regular suit and dress shirt sizing is for a 6" drop, where drop = chest - waist. 8" drop is called “athletic fit”, but is uncommon. Of course, alterations are possible, although it is less likely to be doable the larger the alteration need is.
@Wje916be mentioned that many cities have very good locally owned menswear stores – this is also a good option, if you know where to go. S bought a very nice tux last year at J. Press in Cambridge…they have timeless styles, great service and expert tailoring. I thought the price was reasonable for the quality…it should last him for years.
Forgot to mention, the John Nordstrom line at Nordstrom has quality classic dress shirts at a good price, and they make a trim fit.
I also suggest buying a second pair of pants when you buy the suit - perhaps in a medium or light gray, or tan (depending on what you buy, but assuming dark navy?). This will extend the life of the suit pants and give him more use of the jacket.
@patsmom – I haven’t even clicked through your link but I know exactly what you mean. All of Thom Browne’s suits are like that. Not sure why showing the ankle is the look.
Having said that, son was home during break and bought no-show socks for his J.Crew/Nike special edition sneakers? Guess I can’t buy socks in 6-packs from Costco now.
I have had good luck at Brooks Brothers Outlet when they run a sale, but it can be a challenge for those built like swimmers to find enough of a drop.
Wow @patsmom words cannot even describe how ridiculous that suit looks.
This tight-fitting trend in men’s suits and pants is a little too precious for me, but this one looks like a decent bargain on sale for $600.
I second (or third) Brooks Brothers. A dark suit in tropical wool would be timeless. My husband purchased a BB suit in 1981 for a friend’s wedding and BB tailored it to a perfect fit. Last summer my son wore it to my daughter’s wedding and, coincidentally, it fit HIM perfectly! The wool is fine and the cut is classic. It looked like a new suit.
Athletic cut and slim cut suits and shirts are getting much easier to find for those young men not sporting the Dad Bod. My son is another one who just swims in a Brooks Brothers suit.
I have a related question. What is the most “universal” color these days? I’m thinking either navy or charcoal grey is pretty timeless?
That Nordstrom suit must be from the exclusive Pee Wee Hermon line!
I think so, @1214mom with dark navy the choice of the first suit (or only suit), then dark gray. I think navy gets the nod because it’s a good job interview color.
Suit number 1- navy. Suit number 2 - charcoal gray.
Thanks @Goirmetmom. One of my sons has both blue and black, and the other, who graduates in May, hasn’t had a suit since he was about 5. I offer to purchase, but he’s got to go try them on, etc. he’s a minimalist when it comes to stuff.
I’d go with Brooks Brothers -during a sale you’ll get something nice in your price range. BB does have 3 or 4 different “trim levels” and you’ll find the slimmest to be the most modern fit for the young men today. Their tailor can further fit it to your son’s liking. They also carry or can order up to extra slim shirts. Years ago BB may have had an issue with fit but their newer lines are great. When I’ve looked at Nordstrom - their nicer suits have been in the $1000 plus range.
Second the color choice #1 navy blue #2 charcoal gray
My son is trim build and doesn’t have a problem w BB. I think that’s a dated stereotype of their clothing.
“Second the color choice #1 navy blue #2 charcoal gray”
^^For East Coast. For West, reverse the order.
That’s what I was going to say. Here, the basic color for a suit seems to be charcoal.
One benefit is that it will be appropriate for all but the most dressy occasions where suits are called for. Navy is much more of a daytime color. You could get away with a charcoal suit at an evening semi-formal wedding in a fancy setting; not so much navy.
I guess one advantage of a navy suit is that the jacket can be worn to create the “blue blazer” look when paired with khakis for a slightly businessy business casual occasion. 
Again, this is for the East Coast. Here, that would be “dressy.”
Yeah, the West Coast version of a navy blazer seems to be a nice merino wool hoodie.
Kajon, I love the look of those combat gent suits - and cheap at around $200… I think my son would have been happier with one of those with the stretchiness than what he ended up with… Too late now! Nice parcor (parcour? Not sure of the spelling) in the video.
