Bests & Worsts Reviews from Amazon

I work at a corporate company and I have to dress to impress. I came across this skirt and bought it since I don't own anything grey. I paired it with the FLORIA Womens Classic 3/4 Sleeve Open Front Cropped Cardigan and the Shoes 18 Womens Faux Leather Ballerina Ballet Flats Shoes W/Buckle. At work, my bestfriend told me that I looked like a kindergarten teacher (modest and professional). For references, I am 5'7" and 210 lbs.
