There are some shops I haven't set foot in in years. I'm not a fan of trawling through rails of 'unusual garments' to reach the normal stuff appropriate for someone who's not a stick thin hipster. See here and here for further examples.
Recently I saw 2 different people wearing a top, decided I had to find it and had a couple of hours delay at Gatwick. What's a girl to do? Obviously scour the websites of all the womens' clothes shops you can think of until you find it.
River Island was pretty far down my list. I don't even know when I last went in there. However, I take it all back because it was the source of my current favourite t-shirt. For a bargain £10.
I've only worn it with jeans but I think tucked in to a skirt I could get away with it for work. Hubby says I look like a French flag. Not impressed.
