Here are my top 3:
This long jumpsuit has a cross over front and a palazzo feel to the leg that feels really comfy. If you have a bigger bust you will need a little top underneath but when you put it on you will feel really glamourous and tall. Its £167.00 and comes in several colours.
I actually have this great one shoulder jumpsuit called Betsy and the trousers are great for showing off some fab shoes like my Miu Miu's, it is £97.00 and jersey so will not crease if you are wanting something that will travel well for holidays.
This playsuit is great for any girl who has a great set of pins, again it is quite low cut with the crossover front but is a great addition to your wardrobe for day or night. Its called Apollo and is £137.00 try layering the vibrant yellow racer back T (also from French Connection) underneath for a fab day look.
