How a Christian should dress revolves around a few simple things, first no
cross dressing, second dress modestly, third don't mix linen and wool threads
Leviticus 19:19 "Ye shall keep my statutes. Thou shall not let thy cattle gender with a diverse kind: thou shall not sow thy field with mingled seed: neither shall a garment mingled of linen and woolen come upon thee."
The law which the Lord gave through Moses to the children of Israel forbade "cross-dressing" as an "abomination", a strong word for this immoral conduct.
The main thing is that men are not to portray themselves as women, nor women as men. Women's clothes and men's clothes are very different in appearance and cut, and should be.
