Von, I can totally relate to what you wrote, even though my nude is pretty close to the side of this web page. You have me counting my blessings on that score- thank you!
I do calculate the $80 for practical color (nude or black) vs fun & colorful like purple. My bra drawer is 80% nude and 20% black. My daughter and I had this whole debate recently because she always goes for the fun colors instead, and rags on me for going the practical route. But, she is young and wears a lot of tank tops and such, and showing a hot pink or neon bra strap is totally "the trend" -- fashion intentional!
RE: online ordering -- I've only ever ordered bras that I want to duplicate, i.e., I know the exact model number and size (which is a certain model of Chantelle and has been for many years). I would never risk online ordering for something like this, because out of every 50 bras I try on in the store, I average 1 that fits and is worth duplicating.
My hit rate with bras is far, far worse than anything else -- though shoes are starting to get close to that rate too!
