If being a foreigner in UK and want to buy a shirt you should know that the size of a shirt in UK does not match the size of a shirt in US and you might end up buying a misfit shirt.

The advantages of using a shirt tailor is that you can opt for the cut of a shirt and you will always have perfect fitted shirts.

A perfect shirt in UK and not only should look this way:
&bullThe shirt must be comfortable, not tight, it should not appear baggy across the chest and the shoulders, and it should follow the body line.
&bullThe sleeves must be long enough so they don't make you look like wearing the little brother's shirt when you raise the hands above the head. Also, too long cuffs might also spoil the man's image. Another element that must be remembered is that the jacket that comes over the shirt must not cover entirely the cuffs.
&bullThe cuffs of the shirt must allow the hand move around inside them a bit, so they must not be too tight. When buttoned a perfect cuff will never be able to be dressed by the man.
&bullThe collar of the shirt will also be perfect if you choose a bespoke tailor for making your shirt. A perfect collar can be recognized if entering one finger between the neck and the collar is allowed after the shirt is buttoned.

In UK shirt's fabric is very important. The experienced tailor will use only pure cotton for a shirt as it gives a lot of comfort to the wearer.
Shirts made in UK usually have the buttons stitched by hand and this way they do not become loose in time. Hand-made are the collars of the shirt also and they have removable bones for keeping the shape of the wings perfectly shaped when inserted.

Shirts are very appreciated in UK and will never get unfashionable as they make men look serious, attractive and successful.
