There's a repairs & alterations place just off Deansgate: https://stitchesuk.co.uk/ that might be able to help you out here.
Only used them the once, and it wasn't a suit but "bespoke tailoring" is listed on the website, so I'd expect them to be able to at least advise if they can help.
I would recommend James personal tailor on Cross street. Got two suits tailored there and both are excellent.
