I don't think I should have to say this, and since your here, you probably know better, but nevertheless I observed both of these this weekend:
-Sleeve tags of all jackets are meant to be removed upon purchase.
-Vents and pockets that are sewn together are also meant to be cut open before wear.
-If your suit or blazer jacket (or any other article of clothing) covers most of your hand there is a problem.
Speaking about such matters, it would also be advisable to remove tags off scarves. This is just a small detail that is easily fixed, so why not do it?
