In the past I noticed that items in store are about the same in Europe and the US, so I just thought I'd post this: H&M has quite a large selection of cascading cardigans at the moment.

Many different fabrics and colours (I saw charcoal ones, black, white/black stripes, dark navy/grey stripes, burgundy, dark tealish blue, light grey...). Most of them under $30.

And if someone is looking for a fun jacket with a bit of a military vibe, Mango has a cute one in a dark plaid (matching pants were available too):

The blouse under this jacket (can't find it separately on the website) had potential too. I didn't try it on though.
