I finally found the holy grail, I've been looking for a pair of skinny overalls for awhile now (since the US summer) and saw some super cute ones from Black Orchid which sold out pretty quickly, then I haven't found anything else since. However on the opening weekend of the Macquarie Centre, where H&M also newly opened, I found these in my size! Amazing. The trickiest bit was trying it on, and it isn't the most glamorous thing in the world, but I wore a flared skirt and a simple fitted cami so I can try stuff on either under the skirt or over my top. This way I didn't need a fitting room, which was convenient in the end because the line went from the back of the store to pretty much the front of the store.
