Even close friends won't tell you if you have sweat stains

It got chilly again this weekend. Which is kind of great considering how unbearably humid it will be soon. It's already stifling in this train car. This makes the Wacoal ads for sweat-guarding clothes seem like a good idea. Notice how this ad uses diagrams, fear tactics, reassurance and a pretty western lady in Japanese clothes to make the pitch. Not to mention a clever pun for the name of the shirt itself, sugoi.

I rounded up a few of these breezy duds on Pulse. I didn't mention it there, but my resident aviation expert says that Toray, the textile company behind some of the performance fabrics, also makes the carbon fiber wings of Boeing's 787. I think that could make for an interesting ad campaign.
