Bellbottom trousers are a classic fashion statement that never goes out of style. These trousers are widely known for their flared legs and iconic shape. However, there are several synonyms for bellbottom trousers that are worth exploring. Flare pants, wide-leg pants, and bootcut pants are all variations of bellbottoms. Flare pants differ from bellbottoms in that they have a less visible flare at the bottom of the leg. Meanwhile, wide-leg pants have an all-around looser fit throughout the leg and are moderately flared. Finally, bootcut pants are slightly flared but can be distinguished by their tapered leg and narrower flare at the bottom.
