I had taken a pair of trousers to be taken in and rather than trying them on and allowing Mariana to Pin them I brought another pair of already tailored trousers which I was happy with and asked her to match them (because I was too lazy to get pinned).
She matched them to the last millimetre, I was stunned at how well she did the job after having bad experiences with other drycleaner tailors. Once I took them home and tried them on they opened slightly at the calf, this was my own fault as I had bulked (gym) up since I last wore the tailored trousers she used to match. She took them back happily and double stitched them without charge and then offered me a discount on separate pair of trouser that I had given her (this time I let her pin them).
She has done a wonderful job albeit with tapering requests.
