Can costumes be bought directly?

That means no gacha for looks. You see the item, you see the price, you decide. The only thing standing between you and a costume is whether you can pay for it, which turns wanting a specific outfit into a budgeting problem rather than a luck problem. It also means there is nothing to farm for a particular costume and no pity counter to grind toward.

Paid purchases in Aniimo are aimed primarily at cosmetics and skins, so money buys appearance. Not every cosmetic sits in one place, though. Accessories are sold at specific in-game stores, so finding the piece you want is partly a matter of knowing which vendor carries it.

Check the currency before you get attached to something. Aniimo runs several separate currencies at once, and a price tag tells you nothing about whether you can pay it until you know which pile it draws from. A balance that looks healthy in one currency does not help you at a counter that wants another.

Not settled: How far the paid shop reaches beyond cosmetics is not settled. It may stay limited to paid cosmetics, or it may also carry battle passes, decorations and optional gameplay utility items.
