I almost forgot, I also made this outfit for interviews and smartish occasions. Apologies for the embarrassingly awful selfies (I'm not used to it!). No pattern used, just lots of scratching my head and looking confused!
The top is made from an ordinary stripy jersey and the skirt is from a navy slightly stretchy twill. The skirt has a pearl button on one side and a popper on the other. With the pink belt added I think it looks smart but not too boring.
