Considerations:
Firstly, these shorts are designed to fit persons with a fairly thin physique; The following list is a general guideline for Ideal body weight for these shorts:
6\\\\\\\\\\\\\\\' 0\\\\\\\\\\\\\\\"+ ----- < 165lb
5\\\\\\\\\\\\\\\' 11\\\\\\\\\\\\\\\" -------<160lb
5\\\\\\\\\\\\\\\'10\\\\\\\\\\\\\\\" ------- <155lb
5\\\\\\\\\\\\\\\'9\\\\\\\\\\\\\\\" -------- <150lb
5\\\\\\\\\\\\\\\'8\\\\\\\\\\\\\\\" -------- < 146lb
5\\\\\\\\\\\\\\\'7\\\\\\\\\\\\\\\" -------- <142lb
5\\\\\\\\\\\\\\\'6\\\\\\\\\\\\\\\" -------- < 138lb
5\\\\\\\\\\\\\\\'5\\\\\\\\\\\\\\\" or less -- < 134lb
Beyond these suggestions, if you have a natural waist under 34\\\\\\\\\\\\\\\" Measured AT BELLY BUTTON LEVEL), a natural hip measurement under 38\\\\\\\\\\\\\\\" (MEASURED AT FULLEST PART OF BUTTOCKS), and upper thighs under 24\\\\\\\\\\\\\\\", the shorts will likely fit you with good results.
It is important to realize that everyone\\\\\\\\\\\\\\\'s physique is different; As such, these shorts will have an entirely different effect on each person that wears them.
If you are outside of this range, the shorts can still be worn, but they may be tighter in fit and the overall effect may not be as dramatic.
This product is made of medical grade silicone, which is, at the end of the day, an insulator; If you are wearing these shorts in a warm and/or humid climate, you will find that the region of your body covered by the shorts can become quite warm, and as would be expected, will perspire. This can be minimized by wearing a pair of spandex bike shorts or shape wear between your skin and the silicone which will help to both form a barrier and absorb perspiration. You can also try applying an antiperspirant or \\\\\\\\\\\\\\\"sweat stop\\\\\\\\\\\\\\\" to some of the larger areas of your waist and buttocks prior to putting on the shorts.
What they will do, and not do:
What these shorts WILL do is add inches. Size 1: Adds 4.5\\\\\\\\\\\\\\\" to hips (widest part of buttocks) and adds 1.5\\\\\\\\\\\\\\\" to upper thighs. Size 2\\\\\\\\\\\\\\\" Adds 7\\\\\\\\\\\\\\\" to hips and adds 3.5\\\\\\\\\\\\\\\" to upper thighs. They will NOT change other body measurements such as your waist, or make the rest of your legs any thicker or longer than they really are; For this reason, be aware of your actual body before ordering! The larger size shorts are actually quite dramatic in the difference they will make in your shape, but if your legs are to thin from the thigh down, some wardrobe considerations must be made if you wish to wear the larger size shorts.
