Customer Reviews
Got my t-shirts fast
Ordered some plus size t-shirts. They arrived quickly. Fit was good. Material felt soft. Happy with the purchase.
Good camisoles, shipping could improve
I bought a few camisoles and some seamless panties. The camisoles are really nice, good quality fabric and they fit comfortably. The seamless panties are also fine, no complaints there. The website was easy to navigate. My only minor issue was the shipping. It took a full 8 days to get to me after the order was placed, which felt a little long. I've had faster delivery from other online stores. But for the price and product quality, I'd still probably order again.
Consistent quality, reliable service
This was my third time ordering from Just My Size. I usually get their full-figure bras and some high-waist briefs. This time I tried a couple of their minimizer bras. Just like my previous orders, the fit was true to size and the quality was consistent. Shipping always takes about a week to get to me, which I expect by now. It's nice knowing I'll get what I need without any surprises.
Good deal on basics
I was looking for some new cotton jersey panties and found a multi-pack deal here. The price per pair was really good, way better than what I saw at other stores. I got a bulk buy savings which made the whole order worth it. Shipping wasn't instant, but for the savings, I didn't mind. Felt like I got a solid value for my money.
Love my new sleepwear!
I just got my sleepwear gowns and they are so soft and comfy! I can't believe how quickly they arrived. I've been looking for some good nightgowns that actually fit well and these are perfect. I will absolutely be shopping here again for more! My friends are going to hear all about this place. So happy with my purchase!
Decent quality, slow shipping
I ordered a few items, specifically some front-closure wirefree bras and a pair of activewear leggings. The ordering process was straightforward on their website. It took about 2 days for the order to ship out, and then another 5 days to reach Denver. So, total delivery time was around a week. The bras fit well, true to size, and the fabric feels pretty durable. The leggings are comfortable for light workouts, though maybe not heavy-duty activewear. I didn't need to contact support, so can't comment there. Overall, the products are as described, just plan for delivery time.

quick question, can you stack coupons on their site? like, if I have a free shipping code and a percentage off one?
does just my size still do those 'buy 2 get 1 free' deals on bras or was that a thing of the past?
thinking about getting some shapewear from JMS, but how does it compare to Spanx? is it worth it or should I just splurge on Spanx?
hey, anyone ordered from just my size recently? wondering about shipping times to like, Arizona. need some new bras kinda quick.
do their bras run true to size, especially the full figure ones? I'm usually a 42DD everywhere else but sometimes plus size brands are weird.
