Against the haloed lattice-pains
The bridesmaid sunned her breast;
Then to the glass turned tall and free,
And braced and shifted daintily
Her loin-belt through her coat-hardie.
Can't you just picture it? According to the OED a cote-hardie or coat-hardy is 'a close-fitting garment with sleeves, formerly worn by both sexes'; apparently buttoned down the front and reaching to mid-thigh. Doubtless to be found in Pre-Raphaelite paintings of yearnful maidens.
