Just got a new suit (my first 'proper' suit) and I don't feel it hugs me as i'd like it to, especially at the shoulders. If the shoulders are too wide, is that easily fixed? Will it be costly?
Alternatively, can anyone recommend somewhere to buy a suit for a £300 budget that would fit a skinny guy with narrow shoulders? The suit I've just received is a size 34 from SuitSupply.
Unfortunately not--you can't really alter the shoulders.
If you post pics in the Tailor's Fit Feedback thread, folks there can help you decide if it fits.
