“Very good tailors. I have had many of my (2 and 3 pieces) suits altered, and they've done a perfect job. Friendly staff, great advice and professionalism. Highly recommended.”

“Couldn't recommend A1 Tailors more! I brought two football shirts and asked them to cut them in half and then conjoin a half of each shirt to make a 50/50 shirt. There was a very fast turnaround time, and the tailoring was completed to a very high standard.”
— Ian Copper
“I have been using A1 Express alterations since I first moved to London 16 years ago; Ali has done everything from altered suits for weddings, and found ingenious ways to patch up clothes, often with very short notice; I am constantly impressed to be his craftsmanship.”
