Are they Pantaloons, Pantalettes, Drawers, or Bloomers?

What lies thereunder!

In the complex world of today, there are many questions of life, death and taxes to be pondered but for me, as a lover of Victorian fashions, the distinction, if any, between Victorian pantaloons, pantalettes, drawers and bloomers is one that has always intrigued me.  Now, I think I have finally figured it out.  I know exactly what to call those "unmentionables".

Pantaloons: According to costume historian, Elizabeth Clark, "pantaloons are actually men's clothing".  They were "an earlier style of roomy men's trousers, no longer worn in the mid-19th century". 

Pantalettes:  Pantalettes are female clothing.   “They are a much earlier term for underdrawers (1800-1830-ish)" according to Ms Clark.   Over the first few decades of the 19th century, they evolved mainly into long legged underwear for young girls which were visible (and, therefore, femininely frilled) below the hem of their dresses.

Bloomers: Bloomers in Victorian times referred to a style of 'reform' dress worn by Mrs. Amelia Bloomer, rather than to undergarments. The Bloomer Costume consists of a short (knee to mid-calf) length dress, worn over corded or quilted stays and some petticoats, with long trousers of the same fabric beneath them.

Drawers:  Elizabeth Clark says "drawers are the term used at mid-century to describe a cotton or linen bifurcated undergarment for men, women, or children. It's by far my favorite term for that portion of undergarments, because it shows up so often in period sources, including in clothing diagrams and wardrobe notes from period magazines and workbooks, as well as in private letters and diaries, and advertisements. The frequency of the term 'drawers' leads me to believe it is the most common term at mid-century, and therefore, the one I feel people ought to use, for greater clarity in communication."
