Decent style, shipping took a while

Compared to G-Star RAW, Diesel's style really stands out, especially with the 1DR-XS bag. Ordering was straightforward, but the shipping felt a bit slow, though the quality is top-notch once it arrived.

Solid experience, good jeans

I bought a pair of the 1978 jeans during their mid-season sale. The ordering process on the website was pretty straightforward, no hitches there. Delivery took about five days, which was within the estimated window, and the package arrived in good condition. I didn't need to contact customer service, so I can't speak to that. As for the jeans themselves, the fit is great and the denim feels sturdy, like it'll last. They fit true to size for me, which is always a plus when ordering online. Overall, a reliable purchase and I'm happy with the quality of the product.

Love my new jacket!

Got a leather jacket from Diesel and it's fantastic! The quality is even better than I expected. It fits perfectly and just feels really well-made. I've already gotten so many compliments on it, too. I'm definitely going to shop here again for more clothes soon. Highly recommend to anyone looking for stylish, quality pieces!

Good value on sale

I was looking for some new jeans and saw the seasonal sale. Picked up a pair of D-Strukt jeans for about 40% off. That's a solid price for Diesel, seemed like a good deal. Shipping wasn't super fast but it was free, so no complaints there. Worth it for the savings.

What payment methods do they accept? Just standard credit cards or like, PayPal too?

M Mark F. 1 month ago
They take all the usual credit cards and I've definitely used PayPal there before.

Yeah, standard credit cards like Visa/Mastercard/Amex, and PayPal is an option too. Pretty much what you'd expect.

Does anyone know if that welcome offer for signing up applies to everything, like new arrivals?

B Beth T. 1 month ago
Usually not. Most of their discounts, including welcome ones, don't work on new arrivals or those special collab pieces.

I tried using my sign-up discount on a new bag once and it didn't work. Had to use it on something else.

How can you tell if a pair of Diesel jeans is real? Saw some on a resale site and wanna be sure.

S Sam Bennett 1 month ago
Look for the stitching details, the inner tags should be high quality and not flimsy. Also, the wash and distressing are usually really specific on genuine Diesel.

Check the 'Renzo Rosso' signature on the inside and the little 'Diesel' tag. Fakes often mess up those small details or the denim quality feels off. If it's too good to be true price-wise, it probably is.

Are their jeans actually worth the price compared to, say, Levi's? I like the look but it's a big jump.

P Phil Osei 1 month ago
Totally different vibe. Diesel's denim is usually more fashion-forward and has cooler washes. Levi's is classic, but Diesel feels more premium to me.

I own both, and honestly, Diesel feels way more durable and the fit is just better for my body type. Plus, you get some unique designs you won't find at Levi's.

Can you actually use two discount codes at once? Got one from a newsletter and maybe another one floating around.

T Tom 2 months ago
Nah, I tried that before. They only let you use one promo code per order, unfortunately.

Nope, just one. It'll usually tell you at checkout if you try to add a second.
