Meaning:
An acronym of “outfit of the day,” this term refers to what someone is wearing on a particular day, usually in the context of fashion blogging. It can also mean a particularly fashionable outfit, or the photoshoot involved in taking an OOTD photo that one would post on their social network. It’s a common hashtag on Instagram, allowing fashion bloggers to see each others’ outfits. An OOTD is a look, rather than just a collection of assembled clothes. It has connotations of style, trendiness, and being well put together. Chinese netizens, especially those into fashion, have also picked up on this saying.
Example:
A: 你忙什么呢？再不出发我们要赶不上飞机了。
Nǐ máng shénme ne？ Zài bù chūfā wǒmen yào gǎnbushàng fēijī le。
What’s holding you up? If we don’t hit the road now, we may be late for the flight.
B: 再等五分钟。我今天的OOTD还没发圈呢。
Zài děng wǔfēnzhōng。 Wǒ jīntiān de OOTD hái méi fāquān ne。
Just five minutes. I haven’t posted my OOTD on WeChat Moments yet.
