Here’s a little tip from our friends over at Oak.

Their 50% off sale is now 75% off - starting today and going through the weekend.

The best part? Ten more designers are contributing their overstock for the sale, which means there’s lots of new stuff to pick from for those of you complaining that the store’s sold out of what you want.

And here’s a hint - check out the men’s department for some oversize tees and cardigans to pair with skinny jeans for fall.

You’ll thank us later - even if your Amex will not.

Update: Just kidding, the sale is cash only. Oh, and there’s still lots of good stuff left.

Oak is precisely five blocks from our office. We have to muster up all our self will not to stop in every day and buy up the whole store. Their clothes are always cute, always interesting, and most sadly, almost always out of our price range.

So you can imagine our delight when we walked in the other day (you can’t be strong every minute) and a kind sales lady informed us that everything in the store was half off. You wouldn’t know it from the outside - no sale signs, no slashed little price tags, nothing. Apparently, it’s more like a game of pass it on.

And even better, for those of you not in the area? The sale applies to the site, too. Again, no indication of a sale, but you see that everything’s marked down when you click on the actual items.

So seriously, shop. But pass it on.

If you happen to work in an office loft, then you might be familiar with our dilemma:

Lots of co-workers, one big space, one air conditioner.

And if you’re anything like us, you might happen to sit right next to the air conditioner, where it emits its blasts of cold, whip-like wind, and the sleeveless outfit you picked out for the 85+ degree weather outside isn’t helping your situation.

So we were on the hunt for a cute, blanket-sized scarf that we could leave at work for the next three months, when we saw this tiger striped-like cashmere and silk option on Oak.

At $165, it would be the most expensive scarf we have ever considered purchasing, but we see many uses for it once the summer’s over - a cover on the beach, a legit scarf when it goes from summer to fall, a bedspread when we’re not quite ready to blast heat into our bedroom, a turban for late-night silly sessions, etc.

Until then, we’ll just wrap ourselves up in it everyday and maybe growl a little if anyone tries to up the A/C.

I’ve been trying to avoid the OAK store for a week now. It’s been hard, real hard.

But that hasn’t stopped me from clicking through the pages of new things they’re stocking online. Among my favorites are the new styles of Rubber Duck espadrilles.

Reasons why I think everyone should have at least one pair:

1. They’re a cute alternative to boat shoes, but just as comfortable.

2. They come in seven black and white patterns from stripes to psychedelic checks.

3. OAK stocks men’s and women’s styles and sizes, so you can buy a pair for a boyfriend, girlfriend or any friend, really.

4. Ten percent of the sales go back to the workers in Bangladesh and China as bonuses for making the shoes, and other portions of the proceeds go to global charities

6. Because you can never have enough pairs of flats.

When people started mentioning crop tops to us recently, we thought, “No way,” even though American Apparel’s been holding a torch for it for some time.

When we saw some added to Oak’s site this morning, we thought, “Maybe it’s a mirage.”

But when Jazzi told us she saw a girl wearing a red cotton version in the West Village yesterday, we realized that this needs to be addressed.

We can’t really say that we know when this started to come back (is it really coming back?) Maybe it’s a part of the whole return of the 90’s thing (Rachel Green was a big style icon then), or maybe everybody’s over modesty, but we can’t help but think that this one’s a little too early-career Britney and maybe downright ugly to seriously wear outside of the house.

Maybe we could see it with something very high-waisted…? Or over a body suit or clingy tee? Otherwise, we don’t plan on wearing it.

But more importantly, do you?

Now that it’s officially arctic outside, we’re finally breaking down and buying a hat.

But we know from years’ experience that most hats either slip off or get blown off, which means we’ll have to go for something substantial.

Enter the Minsk Hat, available at Oak NYC, from FIT grad Victor Osbourne.

It’ll stay on, cover our ears, and, most importantly, match with everything since it doesn’t really match with anything (and isn’t that the best way to accessorize?)

It’s also a cute, pared down alternative to the all-out trapper hat, so you don’t need to gather all your courage before stepping out into the cold.

With the combination of global warming and the surprising effectiveness of layering, we’ve been holding out on buying a winter coat with little discomfort.

We’ve been eyeing a few voluminous black wool coats that are absolutely perfect for this season’s sculptural silhouette, and we have a couple that we’ve been tracking online. OK, actually it’s more like stalking, but we can’t wait for them to go on sale.

Last week we got an email from Oak NYC, one of our favorite Brooklyn boutiques – and the home of one of our coat crushes. All outerwear was 15% off.

We were tempted, but we held out. Then, this week another email hit our Inbox. Everything in the store is now 20% off.

We felt the tug on our heartstrings, but again declined to purchase.

Our personal rule is that we never buy any item of clothing over $100 unless it’s at least 30% off, and preferably 50% off.

What number do you have to see on the tag before you’re willing to whip out your credit card?
