How much altering do you have to do with your Suitsupply purchases?
If I can get a "Regular"-size (with all of their more classic cuts, like the Sienna and Lazio), I only have to get the pants hemmed & cuffed.
When I need to buy a "Long"-size (because I do not like the super-short look of the Regular size, like the Havana & SOHO) I need to get the pants hemmed & cuffed and also get the sleeves shortened from the shoulder. My tailor here does that for free for me, so I am really lucky :-)
I also sew in buttons for the suspenders & have the belt-loops removed.
