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 360 GSM weight feel like?
Answer 2: At 360 GSM (10.6 oz), this fabric is a heavyweight cotton. It feels more substantial and durable than a standard thin t-shirt, providing better structure and a premium drape while remaining comfortable for year-round wear.
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
This piece is intentionally cut for a relaxed, effortless look with drop shoulders. If you prefer the intended oversized aesthetic, we recommend staying true to your usual size. However, if you would like a closer, more tailored fit, simply size down one from your standard measurement.
Crafted from 100% cotton with a 360 GSM heavyweight, this garment offers a substantial, premium feel that keeps its shape. Unlike thinner alternatives, it provides excellent coverage and a high-quality texture that is perfect for those who appreciate a more durable, luxury-grade fabric in their wardrobe.
Absolutely. We designed this with a moderate thickness that makes it ideal for year-round wear. It is breathable enough for warm afternoons yet heavy enough to layer comfortably during cooler months, making it a versatile staple for any climate or season regardless of the changing outdoor temperature.
To keep your item looking its best, machine wash cold on a gentle cycle and tumble dry on low heat. The high-quality cotton is built to last, but avoiding bleach and dry cleaning will ensure the fabric maintains its soft texture and deep color for years to come.
