Hi neighbor! I'm in Virginia, too🙋🏾♀️.
You won't have too much trouble ordering from Amazon but you really need your measurements. Your EXACT measurements. A 16/18 isn't standard at all. You'll be a L with one manufacturer and at another, it will be a 3XL. With your true measurements, you'll find that you can order with minimum doubt.
ETA pt2 - Check out the clearance sections for QVC, Macy's, and JCPenneys. I've been doing really well there and I'm a 22/3x.
ETA pt 1 - to add some links: Check out the LALAGEN brand. They have some cute stuff. I'm in love with this top LALAGEN Women Plus Size Short Sleeve Flare Peplum Blouse Top https://smile.amazon.com/dp/B097DQXYFJ/ref=cm_sw_r_apan_i_0JQPWQSNE65R8TVW0Q0Y?_encoding=UTF8&psc=1
