I have to go to New York for work for a few days - how I can avoid creasing my shirts and suits when I pack?
Trouser creases
Trouser creases
On my visits to the dry cleaners, they often offer a semi-permanent solution to the creases down the front of the trousers, as I understand it they apply some sort of solution to the inside of the front creases then press it in, dealing specifically with a Lewin suit would you recommend it, I am all for a razor sharp set of creases as long as it does not harm the material!
There is a branded process called 'Supercrease' that some dry cleaners offer, this uses a small amount of resin that is applied in the crease line (inside the garment) that holds the crease in place.
This process is approved by the International Wool Secretariat and should not harm the wool fibres. It is permanent process that lasts for the life of the garment so should only be used once.
Although it may not harm the material, it can look a little artificial - personally I prefer to press my trousers for a sharp looking crease. Also as wool has a natural tendency to stretch (making it great for tailoring), by pressing your trousers, you can bring them back into shape if they have bagged a little at the knee. But If he wants to use this process, I'd suggest checking that it is the one that is approved by the IWS and not a dodgy substitute.
Hope that helps!

Comments
This is a comment on personal preference; while I like to see someone look smart in a suit I find it off-putting when they look like a tailor's dummy. Slightly 'used' looks smart and relaxing and gives the appearance of being approachable; it gives the look of someone at peace with them self.
