Mostly I shop Zulily for clothes and find it's a great way to find good values on both essentials and a couple of brands that I normally pass by due to the regular retail price. Shipping has been prompt and ordering process is simple.
I've never tried to return anything and have only had one true "dud' of a purchase. Pretty good batting average for Zulily.
How to improve? A larger selection of natural fiber clothing pieces would be a treat.
