I couldn’t be more pleased. Sonny took my vision for a jacket and made it a stunning reality. The fit is perfect, the craftsmanship is exceptional, and his service is of the highest quality. My only struggle is what to challenge him with next. If you are considering having bespoke clothing then Grant and O’Sullivan Tailors is where you need to be looking.

Sonny is an interesting and erudite man with a wealth of knowledge and a patient manner.Genuinely made me feel like I was his only customer.Excellent communication and other-wordly service

This is, as far as I am concerned, the best show in town. Sonny is a truly fine professional. Always willing to find solutions to any problem and nothing is ever too much. He provides advice but respects personal preferences, whenever they emerge. He has a good eye for what works and what doesn't for a given individual and body shape. He has tremendous knowledge of materials, styles, and what needs to be done to achieve the client's objectives. I had my first suit done here recently and will continue to buy suits from Grant & O'Sullivan for many years to come. Highly recommended to anyone with a fine taste and a requirement for the best of the best, yet at prices that are not extortionate.

Amazing experience, outstanding service and just the best suit. Can highly recommend Grant & O'Sullivan. Super cute shop in London, Sonny is giving the best advice for the perfect suit and my husband just had the best wedding feeling great in his outfit.

Sonny made a beautiful suit for me to wear to my wedding. It was my first time going to a proper tailor to get an bespoke suit, What initially felt like a daunting task was very quickly made to be an amazing experience, Sonny sat with me and my partner and talked us through the suit creation, helped us pick the different options required and we ended up having a really nice time chatting and laughing together throughout that initial meeting. The entire experience from start to finish was really pleasant, the quality of the suit is top notch and will definitely come back for more clothes from Sonny Highly recommend Grant O'Sullivan to anyone looking for a tailor.

Great establishment, i managed to secure a jacket an hour before an event saving me the pain from getting a tux delivered. Service was impeccable and the owner was incredibly helpful.
