Embellishments are mostly about looks and have little to do with substance or primary functionality.
More often than not, embellishments are pricey enhancements that serve one of two purposes:
1) They provide the illusion of "better."
2) They are there to hide some deficiency or flaw.
We can buy embellishments (literally and figuratively) if we wish. It's just important to remember what we're getting (or not getting) with the purchase.
