1. As soon as the new season's stuff comes out, run to M&S and try on everything remotely trendy looking in your size - stonewashed jeans, waistless trousers, off the shoulder tops (if you dare). 
2. Try and wear clothes that are all the same shade. 
3. Have guts. 
4. If you have cleavage, enjoy it. 
5. Get good underwear. 
6. Tell everyone you've been on a diet.
7. Exercise. 
8. Accessorise - next to exercise in the luscious style-babe's dictionary. 
9. Don't be fashion victim. 

• Wide bottomed pants make you look bigger than you really are so opt for tailored pants instead.
• Wearing skirts or pants with pockets will make your middle look bigger.
• Your dress or skirt hemline should rest at the narrowest part of your calf.
• Slightly full skirts should be longer than they are wide.
• Belts make you seem bigger and draw attention to your middle.
• Pleated skirts or pants add bulk to your mid section.
• Single-breasted jackets can give a slimming effect. Choose a jacket that is nipped in at the waist. This will create a waist even if you do not really have one.
• If you have a round, full face scarves around your neck will make your face look wider while wearing a V-neck will enhance your facial features and give your neck a long graceful look.

1. This one is for women, as make-up can be a friend in this illusion of looking thin. 

a. A good tan can make you look thinner! 

b. The use of a lot of eye make up can make your eyes bigger. 

c. Pay attention to your eyebrows, for the same reasons as in b.

d. You can even make up your legs; yes, really, why not? 

2. This next trick works well both for men and women. 

3. The clothes you wear can deceive the eye as to your true size, and thus make you look thinner:

a. Don’t use clothes that are too colourful, as that will only attract more eyes on the areas that you really would like to hide. 

b. When it comes to skirt length, for those who want to to look a bit thinner than they really are, you should choose knee length skirts. 

c. Another little trick for men and women is to use vertical stripes.

d. Loosen the pockets, and avoid filling them up. 

4. Always be aware of the position of your body and your posture.
