Yes. Women can absolutely hire wedding suits.

Traditional hire collections are generally cut using standard menswear proportions, so the result depends on individual body shape.
For some women, hire works extremely well. Where bust, waist and hip proportions differ significantly from a standard menswear block, made-to-measure or bespoke tailoring can produce a much better fit.

The best approach is to try the options rather than assuming hire will or won’t work.
