I'm sure you look lovely. Chunkier legs and slimmer top looks very feminine.
My tips:
Low wedge if you can bear it, vionics, fly london or ecco do good ortho shoes
A lines really slim
Wear bright lipstick, headband or necklace to keep the eyes up.
Keep the bottom half solid dark colour eg black a line pinafore, black tights, pointed ballerina shoes.
Choose pointed flats instead of square or round toe if possible
Choose high dernier tights with spandex lycra of 180 to 120 dernier to hold you in
Show off your waist with nipped in tailoring, fitted top or waist belt.
I find exercise gave me confidence before my shape even changed, my posture and self esteem and love for my body increased... cheesy but give it a go. i like pilates and yoga as they are low impact, strength and lengthen the limbs.
Wear the outfit you feel self conscious about to a place you dont know with people you dont know. When you see that nobody else gives a fig, nobody is running away or staring in horror.. you will get more comfortable.
