In the '90s, the Gap is where people went to buy simple and reliable basics with no shame. Except for maybe a few fashion-forward or party pieces, one's entire wardrobe could be based off of Gap pieces. From underwear to khakis to the business casual look that prevailed in the '90s, the Gap had you covered. The accessibly priced brand was ubiquitous, and appealed to everyone from suburban families to yuppies to the urban scene.
