Customer Reviews
Quick shipping, nice top
I bought a plus size blouse. Shipping was fast. The blouse fits well and looks good. No complaints.
Good wide leg pants
I ordered some plus size wide leg pants from Dia last week. They got here pretty fast, maybe 5 days. The fit is nice, true to size for me. The material feels good too, not too thin. I'd probably buy from them again when I need something specific. It was a pretty straightforward experience.
Reliable for workwear
This was my third time ordering plus size workwear from Dia. I got a blazer and some trousers this time. Like my previous orders, the quality was consistent and the sizing was reliable. It's always a good place to find professional clothes that actually fit well. They're my go-to for office attire because I know what to expect.
Great value on activewear
I was looking for some new plus size activewear and stumbled upon Dia. I signed up for their newsletter and got a 15% off discount, which was a nice bonus. I bought a pair of leggings and a matching top during a seasonal sale. The total price felt really good, especially for the quality. I usually pay more for activewear so this was a solid find. Definitely felt like I got my money's worth.
Decent purchase, one small issue
I recently purchased a plus size denim jacket and a graphic tee. The jacket is quite good, fits well and the denim feels sturdy. The graphic tee's print was a little off-center, which was a minor disappointment, but not enough to return it. Shipping took about a week, which was fine. The sizing was accurate for both items. Overall, it was a positive experience, but I do wish the tee's print was perfect.
My new favorite dresses!
I just got my Dia Style Box and it's incredible! My stylist picked out two amazing plus size maxi dresses that fit like a dream. I wasn't sure about an online styling service but this was such a pleasant surprise. Everything felt so personalized. I'm definitely going to keep all the items and I'm already looking forward to my next box. I even told my sister about it!

Are their sizes actually good? I always worry about 'plus size' brands still running small.
Thinking of trying the style box. What's the deal with the styling fee? Does it just disappear if I don't like anything?
