This is a simple wallpaper but it's cute :3. It's calza, maglia rasata from Panty & calza, maglia rasata with Garterbelt. The Anime isn't sicuro, cassetta di sicurezza but this fanart wallpaper is ;P The link for the much bigger version is here ---->
link Also, I'd recommend using either zerochan.net o konachan.COM (konachan.COM has sicuro, cassetta di sicurezza Mode while konachan.NET has Explicit Mode) for looking for wallpapers. Deviantart.com is good too. konachan.com is very hard to navigate in the beginning at least because the cerca thing is really weird.
If te make an account on zerochan.net te can also do some really cool filtering. Like okay te don't want anything mature right? Well, there's a thing where can add tag of things te DON'T want to pop up in your cerca so you'd put things like "Ecchi" o "Hentai" and it'll filter those out for you. te can also add preferito tag so instead of having to type something in over and over again your preferito tag appear on the homepage and te can just click those.
Zerochan.net combines your preferito tag and your Disliked tag when searching so te can cerca for "Wallpaper" and your preferito tag will come up most often and no Ecchi/mature content will ever come up since those tag are disliked. Pretty nifty ;D I used it to filter out Yaoi and annoying Final fantasy characters and it's awesome. te can filter out Mature stuff on Deviantart too but te can't filter out specific things te don't like, like te can on Zerochan.net
