Theory Men’s Clothes Review

The brand’s collection is all about amazingly tailored fits and superior fabrics, which is apparent in the Theory coats and Theory suits available on the brand’s website. Let’s take a look at some of their top-selling items for men. 

Theory Tuxedo Shirt Review

Every man needs a perfectly crisp, white button-up shirt that they can throw on underneath a suit or jacket at a moment’s notice, and the Theory Tuxedo shirt is exactly that. 

Fashioned in 100% cotton, so it’s super breathable to wear, this sleek button-up is ultra-modern looking and has a clean-cut design. The front buttons are covertly covered, hidden under a simple placket, and the shirt has a sharp little tuxedo collar, which only adds to its sophisticated feel. 

With polished french cuffs, this shirt could very well sit nicely under any number of Theory tuxedos, or any other suit for that matter. 

The Theory Tuxedo shirt is priced at $195

Theory Stretch Wool Marlo Pant Review

There’s nothing like a great pair of tailored fit, wool dress pants to help you feel ready to crush any business meeting on the books. And the Theory Stretch Wool Marlo Pant is here for that. 

Fashioned in their signature stretch wool from Italy, these Theory mens dress pants are available in a medium-charcoal shade. But, to help with busy schedules, they’re also wrinkle resistant and can easily be matched up with any Theory blazer. 

The Theory Stretch Wool Marlo Pant is currently priced at $180

Theory Suede Jacket Review

There’s something so cool about a good suede jacket because they’re a different look than leather, but they still go with so many different ensembles. If you’re in the market for one, check out the Theory Suede Jacket

Available in the color otter, which is a beautiful light brown, this blouson style jacket is a zip-up style and has easy-slit pockets and a collar that sits perfectly. For comfort and ease, there’s also a partially elasticated waistband around the back of this soft, goat suede jacket. 

The Theory Suede Jacket is priced at $995

Theory Belvin Coat Review

There’s more grungy and causal Theory leather jackets; then there’s the classy Theory Belvin Coat that pairs beautifully with dressy sweaters, button-ups, or any business attire. 

Available in sizes XS – XXL, this Theory coat is considered the brand’s “signature overcoat” due to its pristine, Tuscan wool fabric that’s produced sustainably. It also has a spiffy, stand-up collar, and a classic covered button closure that’s completely effortless and chic. 

The Theory Belvin Coat is priced at $310 (down from $695). 

Theory Women’s Clothes Review

With everything from Theory women’s suits that are well-structured and tailored to fit perfectly, to Theory dresses that are sophisticated and beautifully made, this high-end contemporary brand really runs the full gamut. Up next in this Theory clothing review, we will take a look at some of their bestselling women’s items. 

Theory Tiny Tee Review

If you’re looking for the perfect T-shirt that isn’t boxy or oversized, but actually fits, you have to check out the Theory Tiny Tee

Made in nine different colors, the Theory Tiny Tee is designed to run small and fit snug, so you can size up if you want to give yourself some room. But the great fit is only matched by the quality material, since it’s fashioned in a super-soft Pima cotton jersey for ultra comfort. It also has a simple crew neck and short sleeves for a minimalist look. 

The Theory Tiny Tee is priced between $45 – $75

Theory Sleeveless Dress Review

On the hunt for a simple and refined dress that would look great under a blazer, or even a chunky sweater? The Theory Sleeveless Dress is definitely one to consider. 

As far as Theory dresses go, this one is available in three different colors and is made with “Good Wool” material, which is eco-conscious and traceable. This sleeveless dress is also fully lined, has a simple round neck, and is made to look structured and put together. 

This Theory Sleeveless Dress is priced at $245

Theory Treeca Pant Review

A beautiful cropped dress pant is a must-have in any busy woman’s closet. Which is exactly why the Theory Treeca Pant is well worth the browse. 

Fashioned in a simple style and structured design, these pants have a cropped leg that sits above the ankle and a comfortable mid-rise. These Good Wool pants also feature a slim leg that’s wrinkle and crease resistant. Plus, they’re made to be super breathable, so they’re ideal for summer days at the office. 

The Theory Pants – Treeca is priced at $195

Theory Block Hill Slingback Review

Theory shoes are similar to Theory clothes, since they’re both beautifully made with solid structure and form. And this is exactly the case with the Theory Block Hill Slingback

Available in three different colors, including black, the Theory Block Hill Slingbacks are fashioned in a suede that’s super luxurious to the touch. Plus, the polished leather outsole and wooden heel that’s chic and sophisticated, round everything out nicely. 

The Theory Block Hill Slingback is priced at $320

Is Theory Ethical?

Theory Clothing Review 12

Theory clothing is continually working to become more ethical and sustainable in their manufacturing and production practices. They consider themselves “conscious by design,” since they work with only ethically-sourced materials and have a goal of reaching
100% traceability by 2025.

Who Is Theory For? 

Theory Clothing Review 13

With their tagline “iconic style made effortless,” Theory clothes are great for the business professional who is looking for well-tailored and structured pieces, such as blazers and dress pants, that’ll seamlessly fit into their wardrobes with no second thoughts. 

Based on Theory clothing reviews, customers seem to appreciate the premium materials and attention to detail that goes into every piece of clothing in this contemporary designer’s label. So, the brand really exists for those who aren’t afraid to make investment purchases for items that they hope will last a lifetime in their closets. 

Comparison: Theory vs. Equipment

Theory Clothing Review 14

For this Theory clothing review, it only seems fair to further assess the brand by lining them up with another brand for a little comparison. 

Equipment is a Parisian brand that’s chic, elegant, and often menswear inspired. 

Let’s have a look at some of the similarities between the brands. 

  • Both Theory and Equipment are on the path of being socially responsible and more eco-conscious in their manufacturing 
  • Both brands have higher price points in the $200 – $800 range, depending on what you’re shopping for
  • They both feature tailored and structured fashion items made with premium materials and the finest details 

Now, let’s discuss some of the ways that they’re different: 

  • Equipment offers free shipping and free returns within the United States 
  • There seem to be more opportunities to catch Equipment clothing items on sale, with more discount codes available 
  • Equipment clothing is mainly focused on their shirt collection, whereas you can find a plethora of designer clothes and accessories at Theory
  • Theory has unisex options while Equipment has just women’s clothing 

It seems as though these two designer brands share a similar design aesthetic and price point, but they do differ in their focus and goals.

Theory Reviews: What Do Customers Think?

Theory Clothing Review 15

This Theory clothing review would be incomplete without taking into consideration what the customers who are shopping for this brand have to say. 

Firstly, let’s go to their website and get a general overview of how the customers are rating some of the brand’s most popular fashion items. 

  • Theory Pants – Women’s Treeca Pant: an average of 4.5/5 stars based on 56 reviews, with one customer saying they’re her “favorite trousers.”
  • Theory Mens Tremont Jacket: an average of 5/5 stars based on six reviews 
  • Theory Blazer Women’s Etinnette: an average of 4.5/5 stars based on 47 reviews, with one customer calling it a “well suited beautifully tailored blazer”
  • Theory Tiny Tee: an average of 4/5 stars based on 36 reviews 
  • Theory Shoes – Block Hill Slingback: an average of 5/5 stars based on 10 reviews 

Overall, there seems to be a general consensus about the brand, since so many shoppers express their love and admiration for the designer label. The fit, quality, and flexibility of their pieces are the focus of several, positive Theory clothing reviews. 

On Influenster, Theory has a 4.5/5 star rating based on 155 reviews. On this site, there are a lot of reviews discussing how the brand’s items are perfect for work attire. One customer shared a detailed five-star Theory clothing review: 

I’m a petite person, 5’2 about 110 lbs. and I’ve always had a lot of trouble finding a good business suit that fits my body. I invested in one pair of Theory slacks and a black blazer and could not be more happy with my purchase. I have worn this suit to dozens of interviews and presentations. The quality of the suit has made it worth the money, even though it was a little more than I wanted to spend at the time. I love the classic, sophisticated look of Theory clothes.” 

And even though the pricing was a concern for some shoppers, several did admit that the quality of the items sold at Theory means that each one is an investment piece, rather than something you carelessly throw money away at.  

A customer left a 4/5 star review on TrustPilot about their experience shopping for the brand’s products: 

Clothing fits really well for some body types, clearly well made. Somewhat expensive for what it is though.” 

One of the only things to possibly watch out for with Theory is their customer service. Some reviewers online stated they experienced poor customer support after making an order, such as difficulty contacting the company to rectify problems with their purchase. There also seems to be some concerns about the fact that not all items ship internationally.

But, all in all, most Theory customers walk away feeling satisfied with their structured pieces made with quality materials— which is very clear to see by looking at the countless glowing reviews.
