I try not to spend too much time and energy on clothing and style now, but not paying enough attention when purchasing new-to-me looks like the polo sweater here can end up costing more than the initial buy when it's something I'll never wear .
My thoughts here, after reading so many helpful and insightful comments, are:
When looking to add a new silhouette or cut or whatever it is, don't buy a garment that has too many disparate design elements (as we used to call them back in the day). In the case of the sweater, we have an open knit, basic plain short sleeves (which can be inherently unflattering ) , a polo collar, a v neck AND stripes. Too much going on in one garment for almost anyone (besides the 5'10" 125 lb model in the stock photo) . I cannot actually redesign this in my mind to make it less preppy.
This same issue happened with my first foray into a barrel leg pant: they were first paired (retail options ) with ultra /high rises which NEVER work for me and only emphasize my stomach. So that design element PLUS a new leg cut and I thought I could never wear this look. It was too cartoonish for my liking.... But after persevering and finding a few brands that offer the softer barrel with a mid-rise (i.e. fewer design elements ) .....I'm now a fan.
