Nuuly is a great idea but it feels like the execution needs a bit of help.
Availability - The best stuff is never available. Some items that I've saved have never been available in the season when it would be appropriate to wear it.
Subscription Model - You can't swap out specific pieces that don't work. You have to send all pieces back and wait until your billing date to get new ones or pay the whole subscription fee again (which was recently raised to $95 before taxes for 6 pieces) to swap your order before your next billing date.
Finding Your Fit - They don't include any measurement guides on each item's page. You also can't filter reviews by the very demographics they collect from you and make available about other users (age, weight, height, body type) so you have to manually find them on each review page.
Website - You can't view all reviews at once on a page without scrolling to the bottom and clicking more reviews and you have to comb through hundreds of reviews manually in some cases to find a relevant review for your height and weight.
Reviews - They don't give users prompts to support writing more helpful fit reviews like was the item too big/too small paired with was it too long/too short which are very different questions. You'll see reviews that say "didn't fit" but provide no sense of what that means. Nuuly uses that data for some aggregate size indicator they have indicated on each item's page but its useless since you don't know the weight, height and body type of the reviewers represented in the indicator.
Delivery - Their delivery process is A LOT slower than R2R and you end up having clothes for only 3 weeks after order fulfillment + shipping time. They send you your clothes in a cloth box that can just be easily unzipped yet you get charged if there are any missing pieces in the return.
Selection - All in all, their clothes are "cooler" and more casual than R2Ry items but Nuuly mixes in A LOT of low quality brands or items that are on/about to be on the clearance rack on the site which makes me look at any unfamiliar brands on their site with a lot of skepticism.
Subscription Cost - Given the chance of having a mixed bag or fail order is super high, at best Nuuly costs the same if not more than R2R in terms of price per retained piece that fits/looks good in person/is not worn out/is not stretched...only Nuuly has way less flexibility. It feels like they are making up these retail prices as well as the discounts for the amount of wear on some of the clothes if you were looking to buy.
Support - Support is nice enough to you but offer no solutions for your issues and that's tough when it sounds like Nuuly is far from making the changes everyone seems to be asking for.
Overall, they seem to present a high value versus other rental services but it's only worth it if you're OK to pay the $105+ monthly fee (after taxes) OR if paying that fee multiple times in one month is OK with you to swap your whole order (see Subscription Model section). Skip Nuuly if that doesn't sound appealing or if you only need it to have a few options for a one off occasion.
