Fashion is often dictated by ones geographical location and   age
New York City Fashion, may  generally differ from Montana / Florida or California Etc.  If one liven in a 4 season location, ones wardrobe would so reflect. Crop Tops are nice, though I do not own any. But in NY   to wear one outside from November to late April is unadvised.
I like suits; at least for work. If one is thinking suit fashion, then one would need a rotating supply.
Early Fall Suits / accessory colors  tend to be more earth / rust / orange
Winter Suits are made of thicker material / woo, so they can only be worn in cold months
Spring Suits / colors - accessories probably a little brighter  than winter to welcome the change in season
Summer  lighter fabrics cotton - Linen
Definitely a few year round , work horse suites   in the   200 G   weight range  ( get to know wool weights  )
Throw in the special occasion suit / jacket for holidays - parties that get worn once a year
Top of with 40 pairs of shoes and this makes for a well rounded wardrobe
As some of you are younger / older than others, I want to impart  something that was told to me by a wise man
FASHION changes season to season. That which is fashionable today, may be out of fashion tomorrow. While STYLE is eternal .
