The Quick Review
Nuuly is owned by Urban Outfitters (which also owns Anthropologie and Free People), so the majority of options come from brands in those stores. While you can find work options in there, it's best for casual clothing or for dressy occasions.
Pricing Structure
Nuuly has the most straightforward membership of any company. There is only one option and that's $98/month (plus tax) for one shipment per month. In each shipment, you can rent six items and add up to four items for $22/item.
Sizing
Nuuly offers petite, standard, and plus sizing. However, when I selected plus size, the site went from showing 23, 533 available items to 3,984. When I tried the same thing for petite, it showed 2,856 items. You don't need to be a mathematician to know that both of those are pretty small percentages.
Maternity Section
This is where I got slightly annoyed. They made it difficult to find all of the maternity clothing in one place (here's a direct link so you don't have to hunt for it like I did). Once I got to it though, I was pleasantly surprised. They carry a number of popular maternity brands and non-maternity brands that have maternity clothing. Some of the maternity brands include Hatch, Ingrid + Isabel, Nom, Ripe, and Seraphine. The only downside is if you need clothes for the office, this is not your best option. The clothing seems to primarily be either casual or occasion (like a wedding guest) pieces.
Ease of use
Other than my frustration with finding the maternity section, the site is pretty easy to use. It's easy to look at the clothing and you can mark items that you're interested in for the future.
In terms of renting, they provide you with a bag and return label, so when you're done, you just put everything back in the bag, slap a label on, and drop it off at a UPS or Urban Outfitters. They keep it easy and shipping and returns are free.
Purchasing
If you liked the items you rented, so much that you want to permanently keep them, you do have the option to buy them at discounted price (from what you would find in a store). However, all purchases are final sale.
Stylist's Take
Because Nuuly is one of the services that I used in the past, I do feel like I should share it specifically because I didn't have the best experience. However, my reasons were pretty personal and specific. I only wanted to get petite items and it felt like the things I wanted were never in stock in my size. Second, it felt like I couldn't get the sizing right for me on the items I did get. I ended up only using the service for maybe a month or two. That said, I know people who use and love it. So if you want to try it out, I would still encourage you to!
