Well the difference is, where as Supermarkets may offer you a normal average shirt at a value price that is simply all they do offer. It is a basic fit, pop in choose your size and material, usually only cotton, buy it and away you go.
Thomas Pink on the other hand offers a huge selection ranging from different colours, materials, and styles!
They have: Classic, Slim, casual, evening, polo, and short sleeved for men. With a variety of collars, and cuffs to suit you and they way you like to wear your shirt for different occasions.
For women they have: tailored, city, slim fit, casual, short sleeved and polo. Again, with a selection of collar fabrics and cuff fits!
The only downside to these shirts is because they are specially tailored to suit you and your needs they hold a higher price tag, so for a casual every day shirt Tesco may be your answer.
