Frankly, I'm sick and tired of all these naysayers. Tightlacing, when done properly, is a healthy lifestyle and provides numerous benefits. It can alleviate and prevent all sorts of back problems, leads to good posture, and makes you taller and more confident.
For this, you need a corset that is custom fitted, which will cost a tad over $400 and if worn daily, should last a good 5 or 6 years. But you'll probably want a new one after a year anyway if you have any dedication to it as your body will adjust to it and you may like to be even smaller, at which point you'll have one to wear at night and the other to wear during the day. They should be dry cleaned unless you have a fancy washer like mine, and most dry cleaners won't touch a corset, you have to call around to the better shops.
It's an expensive undertaking.
And it requires willpower, something of which I don't have.
I've bought 4 corsets from c&s constructions through Tom Lierse, they're american affiliate and have always been well pleased.
Lacing it difficult to withstand in the summer if you live in the south as I do.
Might I start up again, yeah. I've only gone a full week at work though. Do I just lace for parties these days? Yep.
My stats: underbust 32", the corset doesn't reduce that a bit since I prefer hourglass styles to wasp waists.
Waist: probably a 29" these days, up from a 27, because I'm trying to gain weight so my titties have some fat to grow with. I used to lace down to 23.5" on a regular basis, having once been at 19" very briefly at a ren faire to show that it can be done. Nearly passed out before it could be taken off though.
Like most things in life, if it's not taken to any extremes, it's perfectly fine.
