Look online at Nordstrom under Shapewear and you’ll see lots of brands and different types of garments. I have a piece or 2 of Yummie, but everything else is Spanx. Spanx comes in different shaping levels so there’s no reason for the stuffed sausage feeling. If your dress fits well and you’re only trying to avoid VPL, you won’t need a high level of compression and you’ll be very comfortable. I find the Spanx website pretty helpful and they also have stores.
When I get really dressed up, I wear a body suit in the highest compression level. It makes the biggest difference in how I look in my dress and I’m not uncomfortable.
