This is one of my favorite tops. I've had it for a couple years, it was a Christmas gift, and the back is completely sheer. I've never dared to wear it without something underneath, or a cardigan over. I've been feeling a bit more daring though, so here's my back. So risque. It kind of is though, for me anyway.
I've talked about body image a couple times before, but I can't stress the importance of positive body image enough. When I was in high school, I was really, really self conscious. Once day, a boy walked up to me and said "nice back rolls" to get a laugh from his friends. I wore a cardigan or sweater to school every day until I graduated after that. Luckily, my teenage years are gone, and I've learned a few things.
Don't listen to anyone. Seriously. Love your body. I promise it's not so bad. I've spent the last couple years learning that my biggest stigmas about myself were extremely exaggerated in my mind. I've never been skinny, I will never be skinny, and I've decided to embrace it instead of moping about it forever.
Please love yourself. You're not too skinny or too fat or too anything. Embrace every "weird" detail. Bodies are so different. It's the best.
(and being a teenager doesn't last forever)
