"Sweet Dream" is an elegant theme for Tumblr totally customizable and pretty good for large blogs.
This theme contains the following options:
Customizable colors, images, links, texts, fonts and icons;
Regulable fonts size;
Some different effects to put on the images;
Header with 1000px wide;
Main menu with 1-6 buttons;
Navigate widget with 1-10 buttons;
Members and affiliates widgets with 1-10 fields;
Members and affiliates images with resolution of 50x50px;
Updates widget with 1-5 fields;
Social media integrated;
Facebook comments on posts (can be disabled);
The theme contains localization (it means that, in the theme, the notes of your posts will be displayed in the language you settled on the Settings of your blog).
All links you put in the theme must start with http:// or they will not work;
You don’t need to fill all fields from the Theme Options, empty fields won’t be displayed on the theme. For example: if you won’t use the affiliates widget you just need to leave all affiliates fields completely empty and the affiliate widget will “disappear” from the theme.
