Does Victoria Dallon Actually Have Large Breasts?
A year or two ago, someone posted art of Taylor with massive tits. Like, a real set of mammary hammers. This was rightly ridiculed by the tumblr fandom. A bit later, someone found art from the same artist of Victoria with equally large breasts, and the fandom consensus was: well at least they got that right. But did they?
I have just completed a complete reread of both Worm and Ward, and it is actually surprising difficult to pin down what Victoria's breast size is supposed to be. At no point in either serial are Victoria's breasts ever described as being large.
Victoria's introduction in the Glory Girl interlude does not mention her breasts at all, and seems to imply that the "sexy" part of her body is her legs.
(The Glory Girl interlude in general is kind of weirdly written; Wildbow doesn't seem to have fully gotten the hang of the strict third person limited POV yet.)
The closest the text comes to providing any concrete information on the subject is in a chapter of Ward, where Victoria is wearing a borrowed Halloween costume sized in men's small, which she says "squashed [her] chest".
In a later chapter, Victoria is designing her new costume, and Chrystal suggests that she go for something that shows off her "assets", which Victoria rejects out of hand. This would seem to imply that Victoria's has "assets" worthy of showing.
Note that the context specifically is that Victoria's forcefield means that she can get away with wearing armor that display her cleavage not that her tits are especially big. Still, we can probably infer from this that Victoria's breasts aren't small.
However, the fact that Victoria's breasts are never described as large probably means that they aren't. In particular, given how prone early Taylor was to noticing other girls' chests, if Victoria's breasts were meant to be notably large, this likely would have been commented on during the bank fight.
The conclusion that I am forced to draw about Victoria's breasts is that they are of average size.
