What it means
Avant-basic is dressing in clothes that try really hard to look avant-garde and arty but are actually just the same trendy pieces everyone's wearing, squiggle prints, asymmetric tops, the exact so-called bold look straight off the algorithm. It calls out fashion that thinks it's edgy but is mass-produced basic underneath. A loving little dig at trying too hard.
Usage examples

"Love her, but the whole look is avant-basic. Every "weird" girl online is wearing the exact same top."
Where it comes from
It's a snarky mash-up of avant-garde and basic, coined online to describe trend-chasing dressed up as originality. The joke is that everyone's quirky outfit is identical.
