So you finally found a suit you love for your big day. Whether it’s off the rack, custom, or a family piece that’s been passed down, there’s one truth that applies to all of them: almost certainly, it needs alterations.
A suit built for the average person isn’t built for you. The difference between a suit that looks like it’s wearing you and one that looks like it was made for you comes down to a few precise adjustments.
Start With the Shoulders
The shoulder is where fit either works or it doesn’t, and it’s one of the primary things that makes or breaks a suits’ fit.
The shoulder seam should sit exactly at the edge of your shoulder bone. If it overhangs, the jacket is too big. If it pulls, it’s too small.
Shoulder restructuring is possible (we do it at Alts!) but it’s one of the most complex and time-intensive alterations on a jacket, and it costs accordingly. If you’re between sizes, choose the one that gets the shoulders right. Nearly everything else on a suit is more straightforward to fix.

A Note on Taking In vs. Letting Out
It’s almost always easier – and less expensive – to take a garment in than to let it out. If you’re between sizes on the jacket body or the trousers, size up and let the tailor bring it in to your measurements. Going the other direction means working with whatever seam allowance the manufacturer left behind, which isn’t always enough. Learn more about letting out garments here.
What to Bring to Your Fitting
It’s simple – bring everything you plan to wear on the day. Your dress shirt affects where the jacket sleeve should end. Your shoes determine your trouser hem length (a dress boot sits completely differently than a low Oxford.) If you’re wearing a waistcoat or a pocket square, bring those too. The more complete the picture at your fitting, the more precise the result.
If you’re still shopping for shoes, bring something close in heel height and sole thickness. And if you’re planning on losing or gaining weight before the wedding, mention it at your first fitting so your tailor can plan the timing of the final fit accordingly.
Tailor vs. Dry Cleaner: Where Should You Go?
For a wedding suit – especially one needing multiple alterations – a dedicated tailor shop is the right call. A dry cleaner with a basic alterations service can handle a simple hem or a button. But for anything involving structural changes, resizing, or a combination of adjustments that all need to work together, you want a tailor who specializes in suits, can translate your needs and vision, and who can look at the suit as a whole rather than a single fix in isolation.
At Alts, we’ve dressed grooms for weddings across New York, New Jersey, and Connecticut – and we’ve handled the complex, meaningful jobs other tailors turn away. If you’re coordinating looks for a wedding party, we can work with the whole group and ensure every suit reads consistently on the day.
On Timing
Plan for your first fitting at least six to eight weeks before the wedding. If you’re working toward a specific weight or physique goal, schedule your final fitting closer to four weeks out. We even offer rush tailoring for tight timelines (it happens more often than you’d think!)
Book a complimentary consultation with us, and we’ll walk through your vision for the day.
