Absolutely love this denim shacket. Its great quality especially for the price. The blue is a large (size up) and its a cute oversized fit. The black is a medium (tts) and I also like the fit of it, not too tight. Jeans are 10 and too big, I would size down if you are in between. I went with an 8. LTKOver40 LTKFindsUnder50 LTKStyleTip
