You are a similar size to me, which is all 100% my fault!
I am not sure if I have a short waist but am quite busty.
For shops I find that Monsoon and Coast are cut in a way that flatter me. I can't wear a suit, but can wear a jacket if it is tailored and nipped at the waist to create shape and a skirt just below the knee or a longer one. A slight kick out at the bottom of the skirt and maybe a ruffle or detailing at the end of a sleeve.
I suit a cardigan, hence the twinsets which for me are a good alternative to a suit.
I struggle with trousers as I have quite heavy thighs, I need to do a slight bootleg to balance out my bum and I wear them long with a heel. I have found that one of the deisgners at debenhams ranges do trousers that flatter me I think it was Gharani Stock.
I have a few pairs of more informal baggier trousers that I wear with longer flowing tops.
Having larger bosoms I need a v neck but not to deep or I look like a tart, I swear by little cotton camis to go under a v neck , saves my modesty when I am bending over and helping pupils at school. Anything that hugs the chest area and flows over my stomach is flattering on me.
In the winter Boots make my legs look fab, have to buy stretchy to go over my calves but as the y nip in at my ankle they are very flattering. If you can afford it Hobbs do really flattering comfortable ones- even worth looking on ebay I saw a pair go yesterday for under £30.
I can never wear a skirt that has a big waistband or any kind of detailing across the tummy as it draws attention to the area.
I dont like my arms so I never wear anything sleeveless, and a slight puff sleeved makes by shoulders look better. A 3 quater length sleeve is good on me as I have nice wrists!
Dress wise I always have some form of sleeve I tend to suit empire line with a fluted sleeve and a v neck in a flowy material. I also have a fab Wrap dress in black that just hits the knee that I glam up with niced jewellery.
Good underwear is a must for us busty ladies as it lifts you and lengthens that gap Cod was talking about.
AS like my bust area I accessorise well to draw attention away from my lower half. I also carry a nice handbag and if I am ever photgraphed sitting down the handbag sits on my lap and covers my tummy!
