Try on a selection of suits and collaborate with our stylists to discover your ideal look. Here, you'll coordinate styles with your groomsmen and experience a stress-free environment while receiving expert advice to achieve the ultimate wedding look.
* Please note that the fitting appointment will be arranged directly by our team

Step 3: Tailoring and Final Adjustments

After selecting your suit, our skilled tailors will handle any necessary adjustments. Your groomsmen will also be fitted in the following weeks.
Your final fitting will be scheduled approximately two weeks before the wedding to ensure a flawless fit for your special day.


From timeless classics to modern trends, our collection of suits and tuxedos caters to every taste and style. Browse through our selection to find the one that suits you best.

“Brian at the Grooms Room was absolutely fantastic for the year we were in an out in the lead up to the wedding.
The private room, the sneaky beverage and the attention to detail were much appreciated and no stone is left unturned.
One groomsman was only coming in the the USA two days prior and Brian and the guys made sure everything was all set up and even fit in the alterations in super quick time.
I would highly recommend the Groom's Room and the guys there - was a pleasure to deal with them and everything on the day looked perfect from suits and ties to the small little pieces like pocket watches and tie clips.

5/5 all day long”

“We chose to go with Diffneys after reading all their brilliant reviews online and the place lived up to the expectations. We were served by Brian at Groom's Room. It was a very relaxed and pleasant shopping experience. I had an idea of what I wanted to get and Brian helped me narrow it down to the specifics and picked the perfect tux for me.

The overall experience right from selecting the tux, to fitting, to helping us find pocket squares matching the bridesmaid dresses - Brian helped us with every details.

Would highly recommend them to anyone shopping for their wedding suit.”

“Brian was an absolute gent to deal with throughout the process and made something that can be stressful an enjoyable experience. I have used Diffneys for years and had complete confidence in them. Went over and beyond to help, accommodate, and work around different timings and deadlines with lads flying in etc. Having a separate space for fittings made the whole thing so much more relaxed. Would recommend the lads to anyone. Thanks again!”

From start to finish it was a brilliant experience! After having initial appointments with other shops, I was blown away by the attention to detail and help given by Gary in the Groom’s room! We had been advised by a friend who used the Groom’s room and we were not disappointed! Constant help, questions answered, alternatives offered to find the perfect fit/suit for our wedding. Gary was always at the other end of the phone for anything that was needed.

I would highly recommend them to anyone getting married and have already said it to a few of my friends that they should go to Gary and the team for their weddings!”
