I haven't worn a cardigan before. Just got one in the mail and it sits just barely below the waist. It's the same size I wear in sweaters though, and none of my sweaters look like that. Is this the way cardigans are supposed to look or should I return it? Thanks.
Your pic is more or less how I like cardigans to fit too. Which is fortunate, since I'm a shorter guy and lots of cardigans naturally fall to that length on me anyway.
The shorter style is somewhat more current however. As you say, there's a strong element of personal preference here. If the OP doesn't like the length of his new cardy, it's should be too difficult to source a longer cardigan from more traditional shops/makers. The trouble is that some of those are not just longer but also a bit baggier. It can be tricky to find a combination of a slim style and a slightly longer than currently popular length if you're not a bit shorter than average.
