Mawson Óssa

I’ve known Grant for a few years, and watched him go from retail into his own business. He’s always taken great care of me. I had a dark navy Irish linen blazer made up for a summer wedding and I’m thrilled with the fit, the fabric and the result. Grant spent plenty of time to make sure the fit was absolutely spot on. Old school service and attention to detail. The quality of the fabric is top notch too. At his price point there is no better.

Great selection of clothes that stand out from most other ateliers. Grants attention to detail and finding the best looks for me is what sets him apart. Very personable and I will continue stock my wardrobe for here in future

O'MAST 17 has been my go-to tailor for several years and since my first expertly fitted suit he has taken care of all my suiting needs with professionalism. Grant is attentive and sees details that most don't and won't bother to address, he is beyond his years, an expert in his field and someone who is always seeking to better himself. Over the years and through our numerous interactions I have gotten to know him very well, he commands true passion and desire to make everyone he works with look and feel amazing, he is nothing short of a perfectionist. Grant is as good as it gets and with sincerity, I thoroughly recommend him as a tailor and as a professional.

Amazing gem! These guys tailored my Italian Tux for my wedding. Over the moon with how it turned out and looked. Perfect fit and such high quality. I am now getting all of my daily suits from here and have a few being made up now. Service is great, Grant is friendly and always have a good laugh with him when I visit. They clearly know their trade, highly recommend.

Outstanding! Grant tailored my wedding suit and those of my two groomsmen. The end result exceeded my expectations. He was attentive and helpful throughout the process, including providing advice on other aspects of groom styling. Definitely went the extra mile and would not hesitate to recommend him.

I recently had 1 tuxedo and 2 suits made to measure for myself and my 2 groomsmen for my wedding through Grant, as well as shirts, bowties, pocket squares etc. Grant was recommended to me by a friend who had recently been married and also used Grant to fit their bridal party. I had also had consultations with about 6 other different outfitters in Sydney and found that Grant was extremely experienced and knowledgeable and was priced quite competitively for the service and quality of product he provides.The entire process from initial consultation, fittings, and final delivery went very smoothly and professionally, and we were all extremely satisfied with the end results. Myself and my fiancé had a loose idea of what we wanted and Grant was very helpful in providing recommendations and guiding us to figure out exactly what we wanted. He was especially helpful in helping us decide what would work best not just for the groomsmen but for how everything would look together with the whole bridal party, and matching the colours/fabric/fit of the suits with the bridesmaid dresses. The 3 fittings we had were fun and went very smoothly, and Grant’s experience was clear when it came to fitting all 3 of us as we all have quite different body shapes.We could not have been happier with the end result, our suits all absolutely perfect and looking amazing on the day. I would certainly recommend Grant to anyone looking to get fitted for their wedding day.

I honestly can't recommend Grant at Mawson Óssa enough. Grant is Incredibly friendly and knew exactly what I was after. He was incredibly patient with me and the end result for my wedding was amazing. I can't wait to go back for another suit.

O'Mast 17 provided me a seamless and stress free experience in buying my suit for my wedding. I was very impressed with the amount knowledge and expertise Grant provided in customizing my suit. He continued to provide top notch service until my suit was a perfect fit. On top of that he also helped me tailor my groomsmen suits with the same level of detail.

This is the best experience I've had buying any item of clothing, ever. Grant offers the highest level of quality service and care!The vision I provided for my wedding suit (and the groomsmen) was pretty bare, Grant being the absolute style master he is guided me through every step of the process. We ended up with a product far superior to anything I could have found on the rack in Sydney (or anywhere), and at a price-point we were all comfortable with. The turn around time was ace, Grant was always there to give updates and he made himself available throughout.The tailored shirts were the icing on the cake. I will never buy a collared shirt from anywhere else now I know what Grant can deliver.I have since bought another suit for my Sister-in-law's wedding, turned out amazing. I'm now looking to create a work-capsule to step up my style game for 2020. I wouldn't trust anyone else, Mawson Óssa are a cut above.

Absolutely incredible experience with Grant. The level of care and knowledge that goes into the tailoring is the best I’ve come across. Grant has a textiles background, and that really shows through the breadth of explanation when guiding through making my suits & shirts. Refreshing experience compared to other tailoring houses, particularly as they offer a real bespoke tailoring service (not just your run of the mill MTM).
