You must be really proud of yourself for losing so much weight, so you are right you deserve a new wardrobe to celebrate. You have a figure that lots of women you kill for, so skim over what you don't like, an accentuate your assets.
I am exactly the same size as you - 8/10 on top, 10/12 on bottom. The part of my body I like least is my thighs, so we must have been parted at birth.
I bought 2 pairs of jeans recently which gave me a total ego boost, both from Topshop - baxter skinny jeans, size 12 PLEASE go and try some on, thay look amazing on and I would never have thought they would. I wear them with tunic tops to hide the thighs. I also got a pair of boyfriend jeans, size 10, totally camoflage the thighs, wear these with layered t-shirts and cardigans.
Another brilliant purchase was a leather jacket, got it from Comptoir des Cottoniers, it's a fitted biker style, looks great with the layered look, and with dresses....
Dresses, I love them, they love me, completely solve the thigh problem, I particularly love A-line ones often use a belt to accentuate small waist.
A-line skirts are great too, skim over thighs. Wear them a lot in winter with boots.
Toned arms are fab - lucky you You can wear vests and slim fitting t shirts, no more baggy ones. How abot an a-line skirt, camisole, pretty cardigan/ denim jacket for taking dc to the park, etc.
Let me know what colours and styles (chic/boho/casual etc) you like and I'll have a look for some links tomorrow.
