Waist Training Corset - corsetforsale.com

An "Hourglass" Figure: This is why most women start waist training. The reason: It works. Corsets "cinch" in the waist and accentuate the curves of the bustline and hips. The degree to which your waistline shrinks depends on a number of factors. We recommend checking out this before and after gallery to see results other women have experienced.
Improves Confidence: This definitely depends on your personality, but we hear from women all the time who have received an immediate confidence boost when they put on their corset and saw their waistline change.
Fashion Statement: It's more common to waist train by wearing a corset or waist cincher under your clothes (stealthing), but many women simply like the way corsets fit with their style and outfits (see some playful examples). This makes it easier to waist train by simply incorporating the corset as an outfit accessory.
Weight Loss: If you wear your corset during meal times (as many full-time waist trainers do), you will find you cannot eat large portions of food. So yes, you can lose weight if you choose to corset for long periods of time (especially before and during meal times). That said, just wearing the corset won't help you lose weight. Corsets don't magically melt body fat ... they simply help limit food consumption when worn during a meal. See also The Corset Diet: Fact or Fiction.
Support the Bustline: Corsets, especially Overbust corsets, help support the bustline. This can be a big benefit for women with larger breasts (even helping alleviate back pressure and pain).
