[huffpuff]

They are either too short or too long

colour: grey / green / black

any suggestions!?!

anyone?!

I have one from topshop. It's green (like Jade green) but looks quite bluey on here:

www.topshop.com/webapp/wcs/stores/servlet/ProductDisplay?beginIndex=0&viewAllFlag=true&catalogId=195 51&storeId=12556&categoryId=93598&parentcategoryrn=93594&productId=471343&langId=-1

Is this too boring? Too casual?

If you suit the neckline.

I like this a lot, also this or this?
