Outfits come from combinations, and combinations multiply. Seven tops and five bottoms produce thirty-five outfits, not twelve. That single fact is the entire argument for a capsule wardrobe, and this calculator makes it concrete for your own clothes.
Counting honestly
Enter only pieces that genuinely combine with the others. A top that goes with exactly one pair of trousers is not contributing a full row to the multiplication — counting it as though it does is how people end up with an impressive number and nothing to wear.
The calculator reports two figures for that reason. The first multiplies tops by bottoms and adds dresses: outfits you would actually leave the house in. The second additionally multiplies by layers and shoes, which is the theoretical ceiling and always flattering.
The interesting output
The most useful rows are the last two: what one more matching top would add, and what one more matching bottom would add.
The answer is usually larger than people expect, and it is asymmetric. If you own seven tops and three bottoms, another bottom adds seven outfits while another top adds three. The scarcer category is where the leverage sits — which is normally the opposite of where the temptation sits.
What a healthy ratio looks like
Divide outfits by total pieces. Under three suggests a matching problem — the clothes are not sharing a palette or a level of formality. Above five suggests a wardrobe doing its job. Above ten usually means the count is being generous somewhere.
The ratio matters more than the absolute number, because it is the thing you can actually improve without buying anything.
