Use the maker's measurement method rather than relying on ordinary clothing size. Height, neck, chest, sleeve, shoulder, and garment length may all be needed, and cassock or sticharion measurements are not always interchangeable. Confirm jurisdictional style, garment pieces included, fabric weight, lining, and liturgical color.

Consider climate, frequency of use, ease of movement, and cleaning. Lightweight fabrics can be practical for warm sanctuaries, while structured brocades create a formal appearance but may need special care. Custom vestments require extra lead time and may have limited returns, so review measurements and embroidery proofs with the maker before approval.
