Saevyan is a bit of a tomboy. Rough and tumble, can be a bit careless. She's a bit of a pyro and loves blowing things up. Despite her tomboy attitude, she loves her hair. She keeps it long and is always changing the hairstyle. As an alchemist, she has figured out how to change her hair color with different extracts and formulas, although the results aren't always as she intended. Thus her hair color is always changing. Currently it is two different shades of purple. At 3'6", she is actually one of the tallest gnomes possible without magic or mutagens involved. The average height for gnomes is just over 3 feet tall.
Here are some reference pictures to show the common dimensions of gnomes in Pathfinder.


As for her attire, she wears studded leather armor and explorer's clothes. Basically, I picture her wearing a white/cream colored blouse under a brown leather vest with brown leather trousers. Over that is a long brown duster with plenty of pockets for her alchemy ingredients. She wears a belt or two around her waist to hold the bombs and extracts she needs for battle.
The picture below is of an elf(or half-elf) alchemist. Saevyan's coat is very similar to his, but not as detailed. Same idea with the belts though, holding all the bottles and vials.
