Alterations to a Aerostitch Roadcrafter

[Oberon]

After recently acquiring one of these fantastic suits from a member of this here parish, I have in true Tosser style gained a few pounds

I know that I can send it back to Aero to have "adjustments made" lol to compensate for my expansion. Is there anywhere in the UK that could do this or is this my only option, apart from loosing a few pounds

All the best,

John
