Short answer
Lingerie should feel snug and secure, not tight. Elastic shouldn't dig in or leave deep marks, straps should lie flat, and nothing should restrict breathing or circulation. A little impression after hours of wear is normal; pain, numbness or red welts are not. If a piece feels uncomfortable, try the next size up or a different cut rather than putting up with it.
