Hi Gemma
only go to a big primark as the littler stores can be disappointing size wise! They always seem to have the tiny sizes left! The good thing about big primarks is that they have a holiday section all year round so loads of bikinis and beach skirts all for no more than £10, bikinis are usually about £4-£6 and then skirts and wraparounds are between £3-£10.
I used to work in france in the summer months and always used to get a summer wardrobe for around £70 and it wasnt just a few bits and pieces, it was about 5bikinis, 5-10skirts, loads of vests and t.shirts and a few little cardigans, flip flops and pums and sandles.Its brilliant coz its so cheap you dont mind if things get ruined or if you have to chuck stuff away once you get home!!
My god anyone would think i worked in the marketing section for them!hahah
