I actually thought the blazer was long and was even planning to have it shortened :). The waist of the blazer has already been let out; the tailor wanted to let out more but I was afraid that it would look too boxy - Now I guess I'll have to visit the tailor again for him to say "I told you so!". As for the sleeves, I thought you're not supposed to show shirt sleeves for blazers? That's why I decided to keep the blazer sleeves like that instead of shortening them. So I should shorten them now then?
I on the contrary love short sleeves even though wearing them makes me look like a Mormon missonary; they are so much more comfortable. Will undone the first button though; I was just testing if it's comfortable to button up.
The blazer is not short but it's not long either. Shirt sleeves should show, and you shouldn't be afraid of less waist suppresion. The colour doesn't look good anyways (is it black?)
If the pants have belt loops, please wear a belt.
