i would gladly make u over, Morena. I think the key is to show off your best bits and wear colours that suit you. And to dress femininely at all times, even if you are going to the gym wear a halter style top or a bikini top over your sports bra to add a girly touch.
Wear earrings, a necklace, femme shoes- not necc. heels but heels if you can. What I found good was to find one or two celebrities who resemble you in colouring and body shape and use what they wear when they are all styled up to give you ideas.
Since you are hourglass, like me I would wear tops that show the tiniest bit of cleavage- not a lot but that fit your bust and tummy well and then wear loose A line skirts or hipsters on the bottom half, wear heels or wedges or in this weather boots. Always do 3 quarter length or longer sleeves or vests with a cute shrug over the top.
Oh and be confident! Always give yourself positive pep talk even when you feel like people might be staring or women at work are wondering why you have changed your style. Another thing i like to do is wear a hairclip with a tiny flower on it above my ear sometimes. i mean small though- anything bigger than a five pence piece is going to feel silly unless u r on a night out.
Just little things like that really. One last thing i do is wear sheer stockings under my work skirts esp. the ones with the seam on the back. Even if only one or two inches are visible because you have on boots or a long skirt I think it just makes u feel pretty and then u act like it too! If you have to wear suits for work then add a pussy bowed blouse, and nice little jewelry. Let me know if u try any of these ideas!
