Cibulkova wore a one-piece cotton blend Lacoste tennis dress that has been around a while this year. Almost like a long t-shirt with drawstring waist. Comfy and pretty on a trim body.
This dress is available online in France (not on the US site).
Cibulkova's racquet is the Dunlop Biomimetic 600 Lite. You can find it at Tennis-Warehouse and tennis-retailers selling Dunlop worldwide.
Loved her strawberries themed racquet bag too -- last year's but still really fun on the hallowed grass.
Alas, today was a different story...same dress but I prefer to dwell on Monday's result. Congrats to Sharapova however.
