I won't buy clothes that don't feel comfortable when I try them on, however I take style into consideration to a much larger extent when searching for clothes to try on in the first place. For all I know, the clothes I don't like are much more comfortable than the ones I own. When it comes to actually wearing them it's pretty much all about style. There are some clothes I own that are really comfy, but look ugly as hell. I only wear the more stylish ones when leaving the house. But saying that, none of the clothes I own are uncomfortable.
