I shopped at Uniqlo's sister store GU to see why Gen Z loves the brand. I was surprised to find some pieces I liked.

GU's tagline is "Tokyo to Soho," so it makes sense that the brand would place its first store in Manhattan's trendiest, shopping-centric neighborhood. 

The displays were simple. Two mannequins displayed some of the latest products for fall.

The store seemed pretty well-staffed. I noticed at least four employees out on the floor, which from my experience working in retail, is normal for the size of the store. 

The newer styles were displayed at the front of the store.

These men's grandpa sweaters were $39.90 and made from a nylon-polyester blend. 

The fashions were simple — most styles were in solid colors and pieces were layered together. 

They looked like the pants I've seen on teens around the streets of New York this summer. 

I assumed they were from the summer season because they came in a lightweight white denim, as well as light- and dark-wash denim.

The men's denim came in light and dark washes, as well as light and dark grays. They were priced at $39.90 per pair. 

The chef pants style has become popular on TikTok, perhaps thanks to the success of Hulu's hit show "The Bear."

Socks came in ankle and crew lengths. The store also carried dress shoes and sneakers for $39.90.  

There were sports bras for $19.90 and leggings for $29.90. 

Most of the clothing in the sale section were women's styles. 

There were several shoppers in the store, but the dressing rooms weren't too busy. I was able to get into a room right away. 

The mirror was a little dirty and I wished it was wider. 

There were plenty of hooks to hang my clothes. As I try clothes on, I like to organize everything by what I still have to try, what I liked, and what I didn't like. 

I haven't been into the cargo pant trend but I was surprised by how much I liked these. The slightly baggy style made them really comfortable, but they also weren't so oversized that they overwhelmed my frame. I could also see them dressed down for weekends and dressed up with a blazer or sweater for work. 

The tucked wide pants were $29.90 and the layered sweater was $39.90.

I was not a fan of the sweater. While I could see the design they were going for, it looked awkward on me. Perhaps my arms weren't long enough, but the sleeves were severely bunchy. 

I really liked how the pants looked in the front, but when I turned around, the fabric bunched in the wrong places around my butt. 

These slacks were a size small, but the white cargos were a medium, yet both fit me well.

I quickly learned that the best way to find the right fit is to look at the tag. In fine print next to the letter size is a waist measurement. Both of these pants had a 26 inch waist, despite being a whole size apart. 

I really liked the olive color of this shirt, but the fit was a little weird for me. It's supposed to be oversized, but the sleeves were just an inch too long and bellowed at the wrist. I appreciated the concept — I could see it in the pages of a fashion magazine. But the fit didn't suit me and I couldn't justify spending $39.90 on it.

I also tried the same shirt in black, but it felt like something I could find in a lot of other stores. 

I actually liked the mini-skirt more than I expected. I was grateful for the shorts attached inside — there's no way I could wear a skirt that short in New York City without worrying about train station breeze. 

But ultimately, I decided the school-girl look is just not my style as a now 30-year-old. I'll leave the super-short skirts in my twenties. 

The dress was also a cute design, but the shape was too boxy. The waist floated around my actual waistline, and the neckline hovered above my chest. 

GU calls the shirt a "bra-feel" t-shirt because it has padding inside. I was surprised to see what was essentially an entire bra attached to the front interior — much more support than I expected. I liked the top, but the bra was too tight in a size small, so I decided to look for a medium. 

There were two different cargos towards the front of the store. There was a parachute cargo pant on sale for $29.90 and a "pull-on" cargo pant priced at $39.90. Both were baggy and oversized, so it was a little tricky to tell the difference. 

I was curious to see how all the styles and fits compared. Instead of paying attention to the letter size, I grabbed the sizes with 26-inch waists. I ended up with mediums in the pull-on and denim cargos and smalls in the parachute pants. 

With a fitted top, the cargo pants kind of looked cool. But as much as I've been embracing more wide-leg pant styles, I wasn't sold on the cargo look. 

Again, I was surprised that these cargos didn't look awful on me. And I liked that in black, the fabric almost looked like a wide-leg dress pant. But ultimately, I decided to hold off on buying a pair. I'm not sure the pants are suited for my personal style, and I'm not one to conform to a trend just because everyone else is wearing it. 

I didn't like the denim cargo pants — the acid wash evoked a costume interpretation of parachute pants from the '80s. 

There wasn't a line, so I went right up to the register. The employee was so quick at ringing me up, I was still pulling out my credit card by the time they had everything in the bag. My total came to $34.80, plus 10 cents for the paper bag. 

I had written off cargos as a trend only for Gen Z, but I don't totally hate them. The super baggy style isn't for me, but I can understand the overall appeal of cargos.  They're comfortable pants and have a cool street-style vibe. 

After my store visit, I could see why GU is becoming popular. It's a one-stop-shop for basics like tees, jeans, sweatpants, and sweaters, but also offers some trendy pieces at affordable prices. 

That said, I did notice some ill-fitting styles and lower-quality fabrics at GU, which is to be expected for a fast-fashion company. While large brands like Shein, H&M, Zara, and Forever 21 are typically the ones called to question for unethical labor practices and overproduction which contributes to landfill waste, these issues are widespread throughout the industry.
