CHICO'S No Iron Long Sleeve Button Up Blouse

Reposhing this item I purchased from @dreerosethrifts. I love it--the color is stunning, and the fabric is crisp and fresh. The blouse is also nicely designed, and well put-together. It looks brand-new. However, although I wear a standard size 2, which is the size of the blouse, it is too big on me. Seems to me it should be a 4. Please keep this in mind when deciding whether to purchase it. (I'm 5'6" 115 #, with a 34 bust) Questions? Leave a comment below!
