Hi Ana, I had to play around with it myself, so this is the recipe: the original link (when you find the item) won't work. However, take the note of the item number, search at Harolds website (upper right corner, where it says to enter the number) for it, and then you'll find the same page with a different address that actually works! I don't know why that is so.
I like that tunic, but they are out of XS. Don't know if the belt it removable, tough they usually are, but if you are really interested you could always contact customer service and ask.
Btw, what/where is Harolds? Department store/catalog? We don't have any on the east coast, and some stuff is quite cute.
