righto, i've looked. you're not making it easy with those blooming sock lines but i agree that your legs aren't your best feature. (although ones that don't look like your legs have been lashed with fabric for 48-hrs previously might be useful as it's hard to see whether you might have a shape to your calf above the ankle, you twit. )
anyway, you REALLY need to make friends with your Mr Seamstress, i think he can help you dress really well.
like you say the skinny trousers are too short but in principle they do look the best, don't they? so more skinny-ish trews for you. but the skinny jeans aren't good unfortunately because it looks like they're too long (and, well, they need to showcase a good pair of pins imo if they're to work).
so... dress still too long and needs taken up, jeans need taking up possibly and the trousers may need taking in but sorting the dress might do the trick.
you have an arse, but in the right trouser that is yumlicious (i have no bum ). someone posted an outfit on here that you liked, a long-line top in red and white with more tailored wide trousers, i think that could be a great look on you, make everything point to your shoulders, neck and chest again, which are rather gorgeous imo.
