I'm not a guy who enjoys shopping for clothes at all. Finding something that looks, feels and fits just right takes a lot of time and energy, and I usually end up making tradeoffs anyway – if something fits well on the shoulders, it may be too broad on the waist, and so on.
However, Son of a Tailor flips that process on its head, and makes shopping so easy. By getting my own custom size, fit is no longer an issue – every garment I've ordered from them has fitted me perfectly. This, added to the fact that they only use premium materials (e.g. Supima cotton, Merino wool, and Tencel) means that these garments look better, feel better, and last way longer than your average piece of clothing.
PS - I also love the fact that every piece of clothing comes hand-signed by the seamstress/seamster who made it :)
