Today's Everyday Fashion: Opposing Values

Have you ever had two values that felt like they were in direct opposition with one another? I'm constantly playing tug-of-war in my head between the value of being frugal, and concern for the environment. Spending money is like pulling teeth for me, so "getting a good deal" definitely makes it easier. In direct opposition of that, is my desire to buy higher quality and less quantity with my clothing budget for environmental and fair trade/ethical reasons. Do I buy $130+ dresses now (seriously considering this one), so that I'm obtaining fewer items with my monthly budget? Or do I listen to my budget-seeking nature that says getting a $98 dress for only $30 is being responsible with money?  I don't think there's one set answer and I don't think it's the same answer for everyone - it's a topic I dive into in depth in my book because there's a lot to consider. For tday, I'm rocking the budget-friendly money-responsible dress. But tomorrow is a new day and another decision!
