Shopping Dilemmas

So after my yesterday trip to our mega-mall I was left with quite a dilemma on my mind. I didn't really buy much, just some pants for work. But while I was in Aritzia I ended up trying on this dress for fun since my friend had a bunch of stuff to try on. I ended up loving it, to my misfortune because it costs $115.. I can't find a picture anywhere because I believe the brand is exclusive to only Aritzia (Wilfred), and Aritzia's website sucks haha. So I will just describe it best as I can. It's kind of an off-white on the top half, I want to say like a sweetheart shaped top? Anyways the bottom half if black, its kind of high waisted where the black runs into the white. That description probably sucked.. Im usually pretty cheap with my dresses.. but what do you think should I buy it for $115?

Im kinda leaning towards buying it, then I can take a picture and you guys can help me decide for real =) but too much or am I just being cheap? haha

I also kinda found a picture of the converse light, yayy
