> if you don't have any health issues that prevent you from doing so, you should be lifting heavy weights with a barbell. Your clothes will fit better
Only if you were wearing poorly-chosen clothes for your existing body before. If you aren't already out on the far extreme of the distribution for height or some set of proportions, you can probably find pretty well-fitting off-the-rack clothes, and if you have, they'll probably fit substantially worse if you change your body shape in any way -- whether its by gaining fat, losing fat, gaining muscle, or whatever.
Unless you're female and then your clothes will fit worse. I have to buy two sizes up in dress shirts and hem the waist down just to fit my shoulders into them.
