Question

When shopping yesterday,she met with a coat which___ her well

suits or fits ? I chose the fits , but wrong fit不也是合适吗？ suit是式样颜色等 fit是大小尺寸 在这fit不是更好啊？

Answer 1

可参照suit 与fit的区别
1）、作动词时fit 分别可作vt和vi，而suit只作vt,并且suit和fit各有不同的意义。
suit:
1) meet the needs of; be convenient to or be fight for 对……方便，适应……的要求
Will it suit (= ) you if I come at 3:00?
— Does the climate suit you / your heath?
— Yes, it suits me fine.

2) (the color or style of a dress or hair) look well
（指衣服、发型等）相配；适合
— Does this skirt suit me ?
— The color doesn't suit you.

fit: be the right size or shape (衣服、鞋子等尺码大小，形状等)合适；合身
The door fits badly. (vi)
The coat fits me well, but the color doesn't suit my trousers.
这衣服很合身，但颜色与我的裤子没配好。

在上一句里suit和fit不能互换，因为由上可知fit只指“尺码大小合脚，合身”等，而suit指“衣服、颜色、发型等相搭配”。如下句：
The job doesn't fit me. (×)
The job doesn't suit me. (√)
（2）作形容词时be fit for 与 be suitable for 可互换。
The job is not fit / suitable for me.

Answer 2

应该用suits,fit sb.是为某人量身（尺寸、大小等）
