THE BASIC J. OLIVIA FIT BREAK DOWN

• Our sizes run in five standard sizes. Extra Small, Small, Medium, Large & Extra Large.
• All pieces are standard sizing unless advised otherwise on the item description.
• Seamless finishes give a super stretchy feel and can stretch out to 1 size bigger.
• If you have larger busts and are interested in purchasing minimal cut & coverage style, we suggest going up one size to your normal t-shirt size unless you are comfortable with minimal coverage.
