I LOVE her bathing suit and wanted to know what designer that is or something very similar to that
PacSun would probably have something similar. Or you could check out surf brands like Volcom, Hurley, Billabong, Roxy, etc. online to see if they have something similar. Looks like something you would find at PacSun though
It is available just around you.
Well i reckon it would be in lots of shops… not that exact one because hers would eb some fancy designers worht liek 5000 dollars and thats lly to spend on soemthign so basic. Ummm try your surf shops (idk what country your from but ustralia has billions
) forever21 has heaps of cute bikinis atm for CHEAP prices 
Try Surfing Brands such as,
Roxy,
Billabong,
Quik Silver
Etc…..
