Before you buy: Fit tips from the TCF fitting room
Think of this as a backstage pep talk. It looks great on a hanger, which is what everyone wants before buying a blazer that makes them look like they’re being held hostage by their real body.
Features shoulder seams. If your blazer’s shoulder seams are sliding down your arms, try sizing up and adjusting your waist. Don’t size down and spend your entire workday fighting to fit. The shoulder isn’t something a seamstress can easily fix, so take it off the rack so everything else can be adjusted.
There are no compromises when it comes to stretch pants. Clean-cut ponte or scuba fabric pants are more professional than stiff pants that tug at your hips and remind you of their presence every time you sit down. Comfort is not casual. Comfort is leverage.
In most office environments, Midi beats Mini. Midi dresses and skirts fall below the knee and add sophistication to almost any dress code without making any special effort. This is the ultimate “look effortless” silhouette.
Tuck is your best friend. Half- or full-tuck your blouse into high-waisted pants to create a waist without the need for a belt, a prayer, or a second opinion. Once you try it, you’ll wonder why you left it alone until now.
One pattern at a time. Mixed prints definitely work, but in a business casual context, let one piece take center stage and keep everything else clean. Save full pattern crashes for the weekends when the stakes are lower and the energy is higher.
Customize one. Choose the blazer or pants you wear most and incorporate them. If you go from $15 to $25, your $40 clothes will look like $150 clothes, but no one but you in the conference room will be able to tell the difference.
Here’s the truth no one mentions in their workwear guides. The clothes are easy part. What is more difficult is forget to learn The idea that you have to earn the right to take up space in the room. you do not. Therefore, wear a blazer that fits. Buy pants that stretch. Please customize. And I walk into every meeting, every pitch, and every Tuesday as if I already know how it’s going to end. because you do.
