The phrase "more shipshape" implies that something is organized, tidy, and in order. Its antonyms would be words like cluttered, disorganized, unkempt, chaotic, or messy. Such words describe a state of disorderliness that lacks structure or arrangement. For instance, an untidy room, an unkempt garden, or a cluttered workspace would all be the opposite of being "shipshape." Sometimes, things can be less shipshape without being completely disorganized, like when something is slightly messy or needs a bit of tidying up. However, to be "more shipshape" means that something is in its optimal state of cleanliness, organization, and orderliness.
