Do you have women's sizes?

There are no women-specific shirts: every adult shirt is unisex. If you usually wear a women's size, go one size down in unisex (a women's L is usually a unisex M).

So a quick way to pick:

1. Start with the women's size you normally wear.
2. Go one size down in unisex.
3. Between sizes? Go up one.

The size guide has the measurements. Lay a shirt you love flat, measure it, and compare. That beats guessing every time.

Unisex has a straighter, roomier cut than a fitted women's tee, which is good news if you like a comfy shirt for cleaning enclosures.

Wrong pick anyway? You can swap it. See wrong size.
