In this tutorial, we learn how to properly fit a blazer or suit jacket. First, try the blazer on and make sure it is not too baggy or too tight. You want the buttons to be able to close and you want the sleeves to be long enough to reach your wrists. If you need to get it altered to be shorter, mark where it should be, then bring it to a tailor to get altered. You wan to make sure the inside lining of the jacket is sewed on properly and that the shoulders are not too pointy or high. Once you have all these things inspected, make your purchase and enjoy your new clothing item!
