2. Select product suggestions Asos then select product “asos-963913 ♂”
3. Select fitfinder and fill accordingly until you reached “what kind”
4. Choose any brand and press next to select size
5. After selecting size, tap next then press back again as if to adjust size

User will have to re answer the questions again.
