Questions
For any shipping-related questions, contact us at:
support@alchemistethos.com
Question 1: How does the sizing work, and should I order my regular size?
Answer 1: This item is designed with an oversized fit and drop shoulders for a relaxed, effortless drape. If you want the intended loose look, order your standard size. If you prefer a more traditional, closer fit, we recommend choosing one size smaller than usual.
Question 2: What does the 305 GSM weight feel like?
Answer 2: At 305 GSM (9.0 oz), this fabric is a heavyweight cotton. It feels noticeably thicker and more durable than a standard long sleeve tee, with better structure and a premium drape — ideal for autumn, winter and spring.
Question 3: What are the recommended care instructions to prevent damage?
Answer 3: To maintain the quality of the 100% cotton fabric, machine wash cold on a gentle cycle (30°C) and tumble dry on a low setting. Avoid bleach and dry cleaning, and ensure you use a cool iron without pressing directly onto any prints.

Frequently Asked Questions
Find quick answers to the most common questions about our product.
This tee is cut with a relaxed loose fit and dropped shoulders for an oversized streetwear silhouette. For a closer, more standard fit, size down one. Stay true to size for the intended relaxed oversized look, or size up for an even more exaggerated drape.
It’s 100% cotton at 305 GSM (9.0 oz/yd²), giving it a dense, heavyweight feel that’s soft and comfortable. The clean structure and intentional drape help it hold its shape through daily wear.
It’s best for autumn, winter and spring. The 305 GSM heavyweight cotton works on its own on cool days and layers easily under a jacket or overshirt when it’s colder. On hot summer days it may feel warm.
Machine wash cold (30°C) on a gentle cycle. Do not bleach. Tumble dry low or hang dry. Turn it inside out before washing to help preserve color and keep the fabric looking fresh. Iron at low temperature if needed, and avoid ironing directly on any prints.
Like most 100% cotton garments, minor shrinkage can occur — especially if exposed to high heat. To minimize shrinkage: wash cold on a gentle cycle and tumble dry low (or hang dry). Following proper care will keep the fit consistent wear after wear.
No — the 305 GSM heavyweight cotton is dense and opaque, so it isn’t see-through.
