I'm always a little offended when people buy me clothes that are way too big. Someone bought me a shirt that was a 3X for my birthday.
At the time I wore about a L/XL, so I was just sitting there thinking, "Is that really what I look like to you????" It wouldn't be a problem if I were closer to it, but I was definitely offended. Now I'm about a medium, so a 2X would probably tick me off (unless it was someone who hadn't seen me recently). It doesn't bother some people, but I'm a little sensitive about it.
