Welcome to ECF, and I (honestly) tend toward less girly setups. A possibility might be a pico kit in pink, or they also make resin ones that are pretty, or rainbow. I'm not sure the pico "kit" may be the best choice as a starter setup the Melo III is a bit of an airy tank. If you are looking for more clouds though, that may be a spot to start.
I started with a black and grey Aspire zelos setup, it's not adorable, but it's small, reliable, and a good starter setup. Internal battery (the current pico newest kit is a removable battery, if that makes a difference to you.)
I might suggest the Vapresso tarot mini, if you want something small (and pretty) it vapes very nicely although it's also an airier tank (I run mine at 0.5 resistance, which is really more on the sub0hm side, although not as cloudy and low as many sub0hm tanks) and at about 23 watts. The tank is fairly small for that resistance at 2 ml, but it is definitely a "pretty setup."
I might take a look around the form and some reviews, and see what appeals to you. If you want something small, slim and more cigarette-like those starter options exist too. There's an Ego Mega V2 "stick" kit (although it can sometimes be hard to find in stock) that I think looks neat and offers a wide range of colors. If you land on that one, you should know the magic of this tank is in the coil which you need to purchase separately, the Joytech CLR coils, probably starting at 1.0 resistance. They have good longevity, they can be rewicked pretty easily and they offer excellent MTL flavor. With that coil, it's a setup that can shine.
Best of luck and welcome to ECF.
