Creasing is the least of your worries.
Having spent a good amount of money on suits I bought online, I say skip it altogether. Somebody mentioned the same thing to me when I asked the same question, but I didn't listen. I have now a half a full closet of suits, SC and trousers that I never wore nor will ever wear.
I have two from the first batch/kickstarter days - Heavy Japan and American. Both size 32. The American was off by an inch making it very tight and too tough to button. Gustin did offer to take it back and replace it. I have 1776 in 33 slim which works better for me. Never actually measure them since them fit me better.
They are from No Man Walks Alone.
