I was browsing in H&M yesterday for my DD1 who is 10 – when I stumbled across a wonderful shirt in blue cotton with just the right small collar that i'd been looking for for a while :
clair
the cotton is lovely quality just the right thickness and very soft, and I bought it in size 12-13 – 14+ was a bit too long over my bum 
I had never thought that something from their teen section would look good on me, it was a great surprise – and only 15€!!
(I am now wondering if I should look in the teen section of each shop first just to avoid the price difference – even though it was the cut I loved on this shirt)
Anyone else had a nice surprise somewhere unexpected?!
