Lace by LJ Rainbow Long Sleeved Mini Dress Review

The good and the bad

What works

• Sheer open mesh built specifically for layering over swimwear or lingerie
• Stretchy nylon and spandex blend gives a forgiving, close fit
• Bold rainbow pattern and low-cut back make it a genuine statement piece
• Lightweight and breathable, so comfortable worn over other pieces
• No batteries, charging or upkeep beyond gentle washing

What to be aware of

• Sheer by design, so it needs something worn underneath
• One-size fit means the closest fit lands mid-range, less certain at the extremes
• Hand wash only, no ironing or tumble drying, so it takes more care
• Delicate mesh is more prone to snags than heavier fabrics

Buy it if

Anyone wanting a playful, colourful cover-up to layer over a bikini or a matching lingerie set, and who is comfortable with a sheer, attention-drawing look. It suits a UK 6 to 12 frame best around the middle of that range.

Skip it if

Not for anyone looking for coverage or a piece to wear on its own, or for those who want easy machine-washable clothing. If you fall at the far ends of the size range or want something more structured, look for a fitted garment sold in defined sizes.

Design and materials

The dress is made from a 95% nylon and 5% spandex mesh, an open net construction that is sheer throughout. The rainbow pattern runs across the long sleeves and the body, and the low-cut back is a deliberate flourish. The spandex content gives the fabric stretch and recovery, which is what lets the mesh sit close to the body.

Because the whole garment is sheer by design, it is intended to reveal what is worn beneath it rather than conceal it. That is the point of the piece, but it does mean it will always be worn as a layer, over swimwear or lingerie, rather than as a dress in its own right.

Fit and sizing

This is a one-size garment stated to fit UK sizes 6 to 12. In practice, a single size spanning that range relies on the stretch to do the work, which means the fit will feel most reliable around the middle of the band and stretch more at the top end. The mesh will cling and follow the body wherever it lands.

Long sleeves and a mini length are fixed proportions, so height plays a part too. Taller wearers may find the hem sits higher and the sleeves shorter than on a smaller frame. If a precise fit matters to you, a garment sold in individual sizes will give more certainty.

Care and handling

The care instructions are strict for a reason: hand wash only, no ironing, no tumble drying and no bleach. Fine mesh of this kind is easily damaged by heat and by the friction of a machine cycle, so the guidance is worth following rather than treating as optional.

To keep the shape and the bright colour, wash gently by hand, reshape while damp and dry naturally away from direct heat. It is more upkeep than an everyday garment, so factor that in if low-maintenance clothing is what you want.

How it compares

Within the sheer cover-up category, this piece leans further towards playful and colourful than the more common black lace or plain mesh options. The rainbow pattern and long sleeves make it more of a distinctive statement than a subtle accent.

Compared with a beach kaftan or a heavier cover-up, it offers far less coverage and much more of a show. And against lingerie sold in fixed sizes, the one-size approach trades precision for flexibility. Choose it because you want the bold look and the layering versatility, not because you want everyday wearability.

The bottom line

The Lace by LJ Rainbow Long Sleeved Mini Dress delivers exactly what it promises: a sheer, colourful, attention-grabbing layer for over swimwear or lingerie. If that is the brief and you are happy with a one-size stretch fit and gentle hand washing, it is an easy recommendation; if you want coverage, guaranteed fit or fuss-free care, look elsewhere.
