I started testing these by opening all of them and exploring the specials and deals offers by each app. Then, I compared which apps had more deals than the others. Of the ones with more deals, I compared the value of those deals to the apps that may have had fewer deals, but their deals were better. I also looked at shipping costs for each app. 

Lastly, I compared the quality of clothes sold on each app and the range of options. Some apps only sold clothes for kids, while others had clothes for adults too. We were mostly focused on kid's clothing, so we prioritized apps that prioritized kid's clothes and deals on them.

Pat pat has lots of clothes to choose from for any occasion, plus a great variety of sizes for every age.

New customers are able to get their first few pieces of clothing for only 99 cents, including clothes that usually cost upwards of 15 dollars. There are also tons of other ways to save money, including getting $5 cashback when you refer a friend to shop on the app or getting $3 coupons every time you complete a daily check-in task.

Even after these great introductory deals, we think the normal prices are especially good for the quality of the clothing. There are a lot of great, trendy sets and pieces, and we didn't see anything above $20.

The app also gives free shipping, which was not the case for every clothing app. There is also a community page for users to post photos of their kids and connect with other parents, with cash prizes available for participating in photo contests.

And this app isn't just for babies and kids! They also have matching clothing for the whole family, maternity clothes, and plenty of baby supplies. Overall, great to check out for you and your family.

While it is possible to use a lot of various filters to narrow down your online shopping selections, it does not seem possible to filter by sales. Luckily this isn't too big of a deal since you can still filter by price range, but it would be nice if there was a way to filter by items on sale along with the other criteria. It is also possible to shop by clearance in the clearly marked "clearance" section, but it is not possible to filter by things such as color, age range/size, and price when you are on the clearance tab.

This app is a great option for parents who already know they like this brand. 

Free pickup in-store eliminates shipping costs, which is another perk that is unique to this app. Many clothes we saw on the app had savings of up to 75%, and it does seem as though this brand has regular deals and savings. 

Many of the outfit didn't seem quite as fashion forward or trendy as the PatPat app, but they still had good options, and the clothes seem to be good quality. Like Pat Pat, there are options for family outfits. Lots of families enjoy wearing matching outfits on vacation or on holidays, so this is a nice perk.

thredUP is the best option for thrifting clothing and buying lightly used items. Unlike the first two apps mentioned, this app includes adult clothing too aside from maternity or family clothing. 

If you're interested in apps that aren't specifically just for kids, this could be a great one to use to get clothing for both you and your child. 

The app includes discounted brand name clothes similarly to apps that sell designer clothes for less. It's a great place to get the brand names you like for sometimes less than half the price.

Since second-hand is the name of the game here, some of the clothes may be slightly "out of trend," but honestly that matters much less for kids and babies. Not to mention that it's a great way to get top-name brands for much less.

This app is one of the best-designed apps of the ones tested for this article. 

There are cute pictures throughout the app, and it's easy to navigate so you can find exactly the style and type of clothing you are looking for. It also makes it easier to browse and find inspiration for outfits if you're less sure of what you want or want more of a "window shopping" experience. 

The app offers "secret sales" at did different times that only last a few hours, which is another incentive to visit the app more frequently if you like the clothes, and you can set notifications to alert you to check the app so you don't miss a sale. Plus, with the wide range of sizes and styles to choose from, it should be easy to find something for any child. 

We expected more discounts from 6PM considering this is a discount-specific app, but their kid's clothes were not that inexpensive compared to other apps. This is, however, a great app if you want to get designer kids clothes for cheaper prices. They have discounts on Nike and other name brands for heavy discounts that are hard to find elsewhere.

buybuy BABY is another one that isn't as cheap as we expected. Most of their clothes were at least $12, and we were interested in apps that had clothes for less. The apps we rated often had clothes options under $5, so we prioritized those as our picks.

H&M was not chosen, because their clothes were mostly regular price. They had discount items, but the other apps we rated had more so we prioritized showing those. This app also sells way more adult clothes than kid's clothes and our focus was on kid's clothes.

Another one where the deals weren't very compelling. Most of the Kidizen clothes looked like they were regular price and shipping wasn’t always free. While they had really nice clothes, we were interested in apps that could save you money while providing good quality.

This app was not chosen, because the other apps we chose had much better deals. We also didn't choose this app, because the design was clunky and it was less appealing than the apps we selected which were all beautifully designed.

Other apps we looked at for this just had better deals than Zulily for kids and baby clothes. We also felt that this app was more specific and had less options for the majority of users so we stuck with apps that could be appealing to a wider audience.
