Can sports bras with different support levels be developed under one matching set theme?

Yes, different support levels can belong to one matching set theme if the collection logic is clear. A low-support scoop bra, a medium-support training bra, and a longline bra may use different structures, but they should still share the same color family, trim language, fabric direction, and styling purpose. The risk is treating all bras as the same product. Support level affects underband tension, fabric recovery, coverage, padding, and sample review priorities.
