Aliasing shoulder_bag → handbag
Link to alias

Reason:

Same item, with ~220 posts under handbag and ~60 posts under shoulder_bag, plus messenger_bag, mailbag, and satchel (which may also fall under handbag). Please feel free to add any other tag variations out there than can be aliased to handbag (if they're out there).

Tag Alias:

shoulder_bag -> handbag
messenger_bag -> handbag
mailbag -> handbag
satchel -> handbag

EDIT: The tag alias shoulder_bag -> handbag (forum #255776) has been rejected by @Rainbow_Dash.

The tag alias #15027 shoulder_bag -> handbag has been rejected.
(above line being new alias link style)

Oppose.
Since https://en.wikipedia.org/wiki/Shoulder_bag says
"Shoulder bag may refer to:
Handbag, a bag typically used by women to hold personal items ( https://en.wikipedia.org/wiki/Handbag )
Messenger bag, a bag worn over one shoulder with a strap that winds around the chest (https://en.wikipedia.org/wiki/Messenger_bag )
A single strap satchel" (https://en.wikipedia.org/wiki/Satchel )

Suggest shoulder_bag alias to shoulder_bag_(disambiguation)

(because alternative that comes to my mind is clunky:
alternative is implying both handbag and messenger_bag TO houlder_bag .
satchel (in my opinion) would NOT imply to shoulder_bag because some satchels worn backpack-style (example: https://commons.wikimedia.org/wiki/File:Schulranzen-aus-leder-und-felltornister.jpg at https://en.wikipedia.org/wiki/Satchel )

I think I'd prefer messenger_bag mailbag and handbag each to implicate shoulder_bag

On the subject, maybe we should consider aliasing handbag and purse. Looking it up a purse is meant to be smaller than a handbag, but in tagged images they seem about the same.

I wouldn't consider a handbag to be a shoulder bag. A handbag is a small bag designed to be held with your hand. A shoulder bag is a bag with a strap designed to rest on your shoulder. A handbag can have a shoulder strap, making it both a handbag and shoulder bag, but a handbag isn't always a type of shoulder bag.
