It’s crazy how it happens. You’re idly flipping around late at night for something decent to watch on television and suddenly you’re mesmerized by a commercial for a wacky solution to a problem you didn’t know you had.

Now you’ve got two competing, contradictory thoughts:

1. “That is the stupidest thing I’ve ever seen. Only a lunatic would buy that,” and

2. “I wonder if it works. I think I’ll buy that now.”

And so I did.

I bought six “As Seen on TV” products — fashion and style items — and put them to the test.

There seems to be a bit of an obsession with buttocks and breasts in these TV gizmos. Lifting, enlarging, concealing.

For this experiment, I mostly stuck with above-the-waist anatomy.

• Of the items I tried, the one that sounded the absolute cheesiest turned out to be a favorite. That was Bare Lifts (“The instant breast lift … but without the surgery”).

You slap this sticky crescent on your bare bosom, yank upward and plaster the top half of the thing to your chest. Vavoom, your breasts are 2 inches higher. Call it The Perk-ifier. It works.

Don’t let anyone see these in place. The adhesive adds wrinkles (not a good look). A minor redness resulted from sleeping in them. But they stayed put while running. And, I know you’re thinking it must kill to remove them but really, it’s not a problem.

• On the flip side of breast-related gimmickry, there’s the cover-up Cami Secret , a triangle of lace-trimmed fabric you clip to your bra straps to conceal cleavage in low-cut tops.

I could live with the polyester and the nylon/spandex lace, but the deal-breaker was that the thing wouldn’t stay flat. It wrinkled and buckled. Also, the weird garter clips dug into my skin when I wore a seat belt. A full camisole is better.

• And just in case I wanted to “add a full cup size instantly” there was Strap Perfect , a piece of plastic that turns your regular bra into a racerback model. By pulling your bra straps up and in, your breasts are squished together, giving you enforced cleavage.

It works, but I felt like my bra had been yanked toward my chin. If you hate showing your straps, this is a fast fix, but a racerback bra is preferable.

• Just in time for Halloween! When I looked at myself wearing the Bumpits hair accessory (“Flat hair is so last year”) my very first thought? Bride of Frankenstein.

Or, if you want to look like a ’60s go-go dancer, buy these. Otherwise, take a pass. Especially lousy for thin hair.

• We all have necklaces and bracelets we can’t wear because they’re impossible to close. No more.

Clever Clasp magnet closures work great with a twist-lock feature for added security. The clasps are bulky and cheap looking and can travel to the front of your necklace — but I love them for allowing me to wear jewelry I’d given up on because I couldn’t work the clasps.

• You’ve spent a ghastly amount on a pair of jeans, and they’re the perfect length — with heels. But they drag on the ground in flats. Multitask denim with Style Snaps . Sticky snap-ons let you change the length depending on heel height.

These are a good option for quickly changing pants length, and are reusable — if you’re careful. Also better than a safety pin to close a gaping blouse or tame a curling lapel.

Buyer beware

When it comes to ordering “As Seen on TV” products, ridiculous online processing fees can exceed the cost of the item.

“Free” online additional sets often carry a second huge handling fee.

Delivery sometimes takes weeks.

Buying at drug, big box and convenience stores is cheaper.
