Buying from Indochino can be frustrating because there is so little information with regards to the details of how their remake/alterations process works, mailing back, Customs, etc. on the internet. Sure you can read 100 pages of this thread and see a lot of people b!#ching about them, but it's very discouraging for people trying them out because there is no shared repertoire of "insider knowledge". To add my contribution, Angie @ Indochino says: reduce measurements as if the garment were laid flat. This is in contrast to what others have said and to what some may think is common sense: if the chest is 2" too big (40 instead of 38 inch, for example), then you need to use the +/- buttons to show "-1 inch", not "-2 inch". Hope this info is helpful to others. The part about reducing measurements as if the garment is laid flat makes no sense. When you punch in remake adjustments (using your example needing the chest to go from 40" to 38"), they are then reflected in your measurements on your account. If you only punch in "-1 inch", then your account will be updated to "chest 39 inches". You need to put in "-2 inches" which will then bring your chest measurement to the desired "chest 38 inches". I think "Angie" is confused or misinterpreting the info somehow. If you want the pant waist 0.5 smaller you put -0.5, not -0.25.
