I signed up for a Gwynnie Bee trial through Swagbucks today. I have several friends who use Stitch Fix and love it, but they're sizing doesn't go up high enough. Gwynnie Bee is sizes 10-32, so in theory should suit my 5'10" size 14/16 just fine.
Wanting to maximize my trial, I signed up for the 3+1 for my trial, which means I can have 3 garments out at a time and I get 1 bonus item during my trial. GB is sort of like Netflix for clothes. You choose a plan on based on how many pieces you want to have at home at a time. You place items in your closet and are shipped items based on availability. You do have the ability to prioritize items as well as move off season items to a holding section. Shipping is free and you have unlimited exchanges if a size doesn't work.
