To get the look right, try to mix both very masculine and very feminine pieces. The look that's most 'in' right now, has a bit of a street style twist with that 'I don't care what u think,I'm stylish' thing going on. The absolute must have items are pleat-front trousers and boyfriend blazer. Personally, I pull the look together with a feminine blouse and stilettos. Boxy shirts with a bow tie detail are very on-trend too and fit in perfectly.
If you want to give it a little bit more casual, street feel, mess up your hair, add a red coloured item and leopard print accessory!
One of the leaders of androgynous look for A/W 11 was Chanel who really pushed it far with very slouchy trousers and untidy look.
Below is an example of a set with androgynous feel, mostly by River Island; bow tie by Asos.
