After 3 months of daily wear (yes, even to grocery runs!), here's my brutally honest take on this viral waist trainer:

THE GOOD:

• That "instant hourglass" effect is REAL. I gained 2 inches off my waist measurement within weeks - perfect for squeezing into tight dresses!

• The steel bones are lifesavers for my desk-job back pain. I now sit straighter than a royal guard at Buckingham Palace.

• Surprisingly breathable for latex! I wore it during hot yoga and didn't suffocate (though I did leave a sweat puddle shaped like Florida).

THE BAD:

• Sizing is trickier than IKEA instructions. Pro tip: Order 1 size up AND use the extender - better too loose than cutting off circulation!

• The underboob chafing is no joke. I now layer it over a tank top like it's 2003 and I'm wearing a corset over my Hollister tee.

• Those "temporary" red marks? Mine lasted 6 hours post-removal. My partner asked if I'd been attacked by a very precise octopus.

SWEATY SECRET:

Wearing this during workouts feels like having a personal sauna belt. I once burned 300 calories just vacuuming my apartment - my floors have never been cleaner!

FINAL VERDICT: 4/5 stars. It works almost too well - just be prepared for some medieval-level discomfort at first. Your waistline will thank you, but your ribcage might file a complaint.
