Fit is one of the most important things I look at before buying. I decide whether I want a fitted cardigan for a neat look or an oversized one for a relaxed style. I usually check the shoulder fit, sleeve length, and overall length because these details make a big difference in how flattering the cardigan looks on me.
Style and Design Features I Look For
I like to compare different design details before choosing one. Some of the features I consider include:
- Button-front or open-front style
- V-neck, crew neck, or shawl collar
