A Streamlined Process at Grant & O’Sullivan Tailors
Our Made-To-Measure (MTM) tailoring service differs from bespoke tailoring by fitting you into one of our ready-to-wear garments and then modifying its pattern for a better fit. You have the freedom to select your cloth, lining, and various styling details such as single or double-breasted jackets, peak, notch, or shawl lapels, pocket styles, number of buttons, jacket vents, and trouser cuts.
Modern British Construction
Incorporates a lightweight chest canvas for added shape, lightly padded shoulders, and gently roped sleeveheads.
Italian Shoulder Construction
Provides a softly structured jacket for a refined appearance.
Unstructured and Unlined Garment
Perfect for a more casual look. During your initial consultation, our team will help you choose the construction that best suits your needs.
Our service offerings
Whilst we are primarily a Bespoke Tailor, offering suits to discerning clients in South West & Central London, we also offer a number of complementing services.
Creating a bespoke garment is similar to crafting a personalised piece of art. It starts with taking up to 28 detailed measurements to develop a precise paper pattern of your body.
We offer a number of services to trade clients & welcome any commercial clients to contact us for further details. We offer CMT (Cut, Make, Tailor) services to the trade industry and we are also fabric merchants.
Welcome to the Personal Styling section of Grant & O’Sullivan, where we believe in transforming wardrobes to reflect the unique style and confidence of each individual.
EXCELLENT Based on 22 reviews Gianfranco Merati2024-11-15Trustindex verifies that the original source of the review is Google. 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. Anja Da Silva2024-11-12Trustindex verifies that the original source of the review is Google. 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. Philip von Gegerfelt2024-11-02Trustindex verifies that the original source of the review is Google. 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.

James Jago2024-05-30Trustindex verifies that the original source of the review is Google. Sonny was fantastic from start to finish. I wanted a made to measure suit and was delighted with the amount of design choice this still left (even though it wasn’t ‘bespoke’) as I got to choose fabric, lining, personalisation, buttons, seams, lapels, pockets, pocket angles … Sonny was great at allowing me to choose what I wanted while giving advice as to what he felt worked. The suit fits wonderfully and I’m so pleased with the result. I’ll be back for another one soon and a shirt I suspect … Vivienne Goldstein2024-05-24Trustindex verifies that the original source of the review is Google. Sonny was brilliant with us. My husband has lost a lot of weight and Sonny ensured that the suit, the jacket, a few pairs of shorts and some trousers got fitted to Perfection. And we were treated very elegantly. Great old fashioned service It was a pleasure doing business with Sonny at Grant and O’Sullivan. We highly recommend them Thank you, Sonny Jack Delaney2024-05-03Trustindex verifies that the original source of the review is Google. I bought a suit off the rack almost a year ago which needed a lot of alterations. I wasn't sure it was possible but after a detailed discussion with Sonny, he was able to find the right solutions and turn it around within a week. The suit looks great and I can't wait to wear it at an upcoming wedding this summer. Thank you very much! Aleena Gashi-Dedova2024-04-24Trustindex verifies that the original source of the review is Google. To say I’m impressed, is an understatement. For someone who is very hard to please, and is extremely particular, I’m so pleasantly surprised with my new work attire. Upon confirming my apportionment and having my initial consolation. I have subsequently collected my first full suit from Grant & o’Sullivan. Suit is beautifully made, and fits like a glove. Sonny has my business for life. Quality is hard to find. I’m so glad I happened Upon this gem! Thanks Sonny!! AVerified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.
