At lower levels not much to be obvious- simple hose and doublets pointed together etc.
At a mid to higher level you start to get the more "Henrician" look with slashed and puffed knees and sleeves, waffenfrocks and plastron fronted doublets (the ones that open to the side) and also scooped necks and the like with exaggerated codpieces.
"The Tudor Tailor" gives a good overview.
Equipment wise you have-
bellows faced sallets coming in (gorgeous when done well) along with the more "Maximillian" styles of armour with fluting etc
bases (cloth skirts) worn with harness
quivers worn at the hip by archers
halberds come in from the continent (though bills stick around in certain roles in the UK for another long while)
the import of horses and troops for differing roles to fill in the blanks that cannot be supplied by indigenous troops and breeds.
