Aritzia Green Top And Older Style Lululemon Gray Pants Both Size XS

Aritzia Sunday Best green top brand new, without tags and only tried on. Size XS. Comes with older style Lululemon pants. I’ve sewn an elastic band around them as they were quite loose around the waist. Now they’re too small. Not sure of the correct size but they are lower waisted and probably a size 2 or 4. They were also hemmed at the bottom but taken out.
