The opposite of "one size fits all"

Is there a neat word or phrase that summarizes the opposite of "one size fits all"? "One size does not fit all" is not an option. What am looking for is something that means "different sizes for anybody, for every occasion etc.".

Solution 1:

Here are a couple possible opposites:

• "Made to order" — the product is customized each time to a new specification. This is the extreme opposite.
• "Available in a variety of sizes" — there are several sizes available for the given product.

Solution 2:

Consider custom-fit

personalized with regard to shape and size

A Britishism that is sometime heard in the US is bespoke

(Of goods, especially clothing) made to order: a bespoke suit

Solution 3:

context specific

Implementation of software solutions are typically context specific. The implementation depends on the amount of data used, hardware available, the business user's priorities, the level of ability of the users etc.
