I created this little glossary of different types of tops (and bottoms) when I was writing the book. I was going to include it in the book, but the powers that be decided that it was too long. So, here it goes. Please feel free to add any additional types of tops to the comments section below.
Bandeau Tops: band-shaped covering specifically the breasts
Blazer: generally a long-sleeved sports jacket with lapels
Bolero jacket: a jacket that is loose and waist-length and open at the front
Cap sleeve: a shorter sleeve than normal that forms a stiff cap or falls on to arms providing minimal coverage
Chemise: A simple, straight unbelted dress with different lengths and sleeve styles
Corset top/boned bodice: usually strapless bodice with laces or snap closures that is extremely form fitting.
Cowl neck: a piece of material attached to a garment at the neckline, usually used as a hood or draped loosely at the front neckline or back.
Crew neck: a round neckline that sits close to the base of the neck encircled by a ribbed banding.
Cropped top/jacket: a top or jacket where the hem is cut above the waist.
Dolman sleeve: a sleeve designed without a socket for the shoulder-creating a deep armhole extending from the waist to the wrist. A.k.a. batwing sleeve.
Double breasted: normally a jacket where one-half of the front lays over the other, and usually has a double row of buttons and a single row of buttonholes.
Double-tee top: one t-shirt over the other, giving the effect of layers.
Draped bodice: extra pieces of material laid over the bustline.
Empire waist: a waistline that begins below the bust.
Halter top: a sleeveless shirt that meets on the top of the neckline creating a high choke or wrap neck and is normally backless.
