Y2K-era Forever 21 black waffle-knit thermal top with a fitted silhouette, crew neckline and long sleeves.
Features the older floral “21” label and classic lightweight thermal texture. The narrow cut works well for fitted Y2K, grunge, indie sleaze and layered styling.
Tagged size M/M, but this is a very slim junior-style fit and may fit closer to a modern women’s XS. Please rely on the measurements rather than the tagged size.
Measurements taken flat:
* Pit to pit: 14.5"
* Length: 22.5"
* Sleeve: 24.5"
* Bottom opening: 15"
Good pre-owned condition with light wear and no obvious major flaws observed.
Ships fast from Second Half Supply Co.

We grade every item based on its vintage condition. You'll find the condition listed on each product page (Excellent, Good Vintage, Fair, etc.) along with details about any signs of wear.
Are all items authentic?
Yes — every piece is verified for authenticity before it's listed. We stand behind what we sell.
How long does shipping take?

What is your return policy?
We accept returns within 14 days of delivery, provided the item is unworn and in its original condition.
How do I choose the right size?
Each listing includes detailed measurements. Vintage sizing can run differently than modern sizing, so we recommend checking the measurements against a piece you already own.

Yes, as long as it's returned within our return window in its original condition, unworn, and with tags (if any) still attached.
