Help!

Hi! So I'm new to the forum and new to the hair game, in the sense that I'd never been fully committed. I had gotten weaves here and there before, but now I'm in the habit of getting them regularly. Because I'm a college student, I 1. Hate asking my mom for money and 2. Don't have much of my own. Given my situation, I figured that a upart wig would be the most economical solution for me. This led me to my next dilemma, I'm not good with braiding, sewing, or anything weave related so when I heard that Roman made upart wigs I thought it'd be perfect. I ordered a custom upart with a medium cap in a 10, 12, 14 inch chinese light yaki natural wave. The hair is beautiful. However, the cap is too small for my head. I've only tried it on with my hair blowdried and pulled into a ponytail and I'm getting it braided this weekend. I can only hope that this helps. Also, I'm natural and this hair doesn't blend the way I thought it would. I'm pretty upset because it really bums me out when my hair doesn't look right, a feeling that I'm sure a few of you can relate to. So basically I'm coming to this forum to ask what my options are. Should I put it up for sale? Where? Would people buy it? My options look pretty bleak. 

Was you hair braided when you measured your head for the wig?
