This is always such a sad day. I recently had to shop for a wedding I was attending and realized none of my old go-to outfits for fancy occasions suited me well anymore. My style has changed from feminine and floral to more casual and tom-boy-ish. I too was fighting back tears while looking through clothing racks and not being able to find new dress attire to replace the old. It's tough, no matter what stage of life you are in! Good on you to have hired a stylist at Nordstrom. I didn't even know what was a thing!
Hope you find something new to wear soon; something that is just as faithful as the lady tux has been.
