The Tie Bar on Newbury Street opened in Boston as a pop-up in 2016, peddling jaunty ties, pocket squares, and other accessories for the debonair gentleman on a budget. It’s a one-stop shop for $19 floral bow ties and skinny silk ties with bike or football motifs, $25 herringbone suspenders, or $15 lobster-shaped tie bars. Hey, why not?

But until now, customers had to find the rest of their outfit elsewhere. No more. The Chicago brand has expanded into apparel, with a new line of $75 dress pants. Made of a wool-spandex blend (for stretch), in athletic and trim fits, the line comes in colors such as classic navy, bright navy, charcoal, black, and light gray. They are also flat front without trendy flair, like pleats.

“Our customer is a working professional, and those trendy designs push a little too far for him. Believe it or not, pleats are once again having a moment,’’ says chief executive Allyson Lewis.

Subtle and affordable was the goal, Lewis says, and as a bonus the muted colors let the Tie Bar’s neckwear stand out.

The Tie Bar sells $55 non-iron shirts now, too, in solids, ginghams, checks, and chambrays.

But if this sounds too buttoned-up, remember: You can still go wild with suspenders or crustacean-theme tie clips.

“We want our pants to be complementary to our accessories. We didn’t want to create crazy, loud, bold patterns — we want to let the accessory be your crazy statement piece and for the pants to be a foundation of your outfit,’’ Lewis says.
